• Elevation Gain: 560 feet
• Estimated Time: 1.5-2 hours
• Location: Eastern Honolulu
• Permit Needed: Yes, reservation required ($5 per person + $10 parking for non-residents)

The Experience: “best hiking trails in oahu”
Ascending the rim of Hawaii’s most recognizable volcanic crater, the Diamond Head Summit Trail combines fascinating military history with breathtaking panoramic views. The trail begins with a gradual climb that becomes steeper as you approach the summit, including 74 steps, a spiral staircase, and a narrow tunnel—all remnants of the crater’s military past. “best hiking trails in oahu”

From the observation platform at the top, you’ll enjoy a 360-degree perspective encompassing Waikiki, downtown Honolulu, and the vast blue Pacific. Informational plaques explain both the geological formation of the crater and its strategic importance in Hawaiian defense. “best hiking trails in oahu”

Why It’s Great:
Despite being one of Oahu’s most popular attractions, Diamond Head delivers a genuinely rewarding hiking experience. The varied terrain keeps the climb interesting, and the historic military installations add cultural depth to the natural beauty.

Insider Tips: “best hiking trails in oahu”

• Reservations are strictly required and sell out days in advance—book at gostateparks.hawaii.gov
• Arrive at opening (6:00 AM) for cooler temperatures and fewer crowds

• Bring cash for refreshment vendors at the trailhead

Lanikai Pillbox Hike (Kaiwa Ridge Trail)

Quick Stats: “best hiking trails in oahu”

• Difficulty: Moderate
• Length: 1.8 miles round-trip
• Elevation Gain: 650 feet
• Estimated Time: 1.5-2 hours
• Location: Lanikai, Kailua
• Permit Needed: No, but extremely limited street parking

The Experience:
The Lanikai Pillbox Hike delivers some of Oahu’s most Instagram-worthy views with a relatively short but steep climb. The trail ascends quickly up Kaiwa Ridge, requiring some minor scrambling over rocks and roots in the initial section. Your effort is rewarded almost immediately with spectacular views of Lanikai Beach and the Mokulua Islands (“The Mokes”).

The trail leads to two World War II-era pillboxes (military observation bunkers) that serve as perfect platforms for taking in the stunning turquoise waters and dramatic coastline below. The second pillbox offers the best views and is usually less crowded than the first. “best hiking trails in oahu”

Why It’s Great:
Few hikes deliver such magnificent views with such a relatively small investment of time and effort. The trail’s eastern exposure makes it perfect for sunrise hikes, when the first light of day illuminates the offshore islands and transforms the ocean into a canvas of gold and blue.

Insider Tips: “best hiking trails in oahu”

• For sunrise hikes (highly recommended), bring a headlamp and arrive 30-45 minutes before dawn
• Parking in Lanikai is extremely difficult—consider parking near Kailua Beach and walking into Lanikai
• The initial section is the steepest and most challenging—it gets easier after the first 10 minutes
• Continue past the second pillbox for even more spectacular views with fewer people

Aiea Loop Trail

Quick Stats: “best hiking trails in oahu”

• Difficulty: Moderate
• Length: 4.8-mile loop
• Elevation Gain: 900 feet
• Estimated Time: 2.5-3.5 hours
• Location: Aiea, Central Oahu
• Permit Needed: No, free parking at Keaiwa Heiau State Recreation Area

The Experience: “best hiking trails in oahu”
The Aiea Loop Trail offers a completely different hiking experience from Oahu’s more famous coastal paths. This shaded forest hike winds through a native ohia and koa forest with glimpses of Pearl Harbor and the southern coastline through the trees. The terrain alternates between gentle slopes and moderate climbs, with a few stream crossings and scenic lookouts.

A highlight of the trail is the remnants of a B-24 bomber that crashed in the forest during World War II. Though most of the wreckage has been removed, some pieces remain visible just off the trail as a somber historical reminder.

Why It’s Great: “best hiking trails in oahu”
This trail provides a welcome escape from the heat and crowds of more popular hikes, offering a peaceful forest experience within easy reach of Honolulu. The loop format means no backtracking, and the moderate difficulty makes it accessible to most reasonably fit hikers.

Insider Tips: “best hiking trails in oahu”

• Hike counterclockwise for more gradual ascents and to save the best views for later in the hike
• The trail can be muddy and slippery after rain—check conditions before going
• Pack mosquito repellent as the shaded, moist environment can harbor insects
• Combine with a picnic at the park’s facilities for a perfect day outing

Kuliouou Ridge Trail

Quick Stats: “best hiking trails in oahu”

• Difficulty: Moderate
• Length: 5 miles round-trip
• Elevation Gain: 1,700 feet
• Estimated Time: 3-4 hours
• Location: East Honolulu
• Permit Needed: No, street parking in residential area

The Experience: “best hiking trails in oahu”
The Kuliouou Ridge Trail offers one of Oahu’s most satisfying ridge climbs, traversing multiple ecosystems as you ascend from neighborhood streets to panoramic mountain views. The trail begins gently through ironwood forest before steepening as it climbs through native koa and ohia trees.

After a series of switchbacks, you’ll encounter a welcome flat section through a fragrant pine forest before tackling the final steep ascent via wooden stairs to the Ko’olau Summit. The reward is an expansive view of Waimanalo, the windward coast, and on clear days, distant offshore islands.

Why It’s Great: “best hiking trails in oahu”
This trail perfectly balances accessibility and challenge, offering true mountain terrain without requiring technical skills. The diverse plant life makes it both an ecological and scenic journey, and the summit view ranks among the best on the island.

Insider Tips: “best hiking trails in oahu”

• Start early to avoid afternoon clouds that can obscure the summit views
• Bring layers—the summit can be windy and significantly cooler than the trailhead
• Look for native plants like ‘ohelo berries and pay attention to the changing forest types
• Respect the neighborhood at the trailhead—keep voices down and don’t block driveways

Best Challenging Hikes for the Adventurous

Koko Head Crater Trail

Quick Stats: “best hiking trails in oahu”

• Difficulty: Difficult
• Length: 1.8 miles round-trip
• Elevation Gain: 1,050 feet
• Estimated Time: 1.5-2.5 hours
• Location: Hawaii Kai, East Honolulu
• Permit Needed: No, free parking

The Experience:
Often called “Koko Head Stairs,” this trail is actually an abandoned railway track that once transported military supplies to a WWII lookout post. The 1,048 railway ties form a brutally direct route straight up the side of Koko Head Crater. Each step becomes increasingly steep as you climb, with the infamous “bridge” section midway up where the tracks cross a 12-foot gap with nothing but air beneath them. “best hiking trails in oahu”

The quad-burning climb culminates at a panoramic summit platform offering 360-degree views of east Honolulu, from Hanauma Bay to Sandy Beach, with downtown Honolulu and Diamond Head visible in the distance.

Why It’s Great for the Adventurous:
This is the ultimate stair-master workout with an incredible payoff. The straightforward but challenging nature of the climb creates a shared sense of accomplishment among hikers, and the views rival those of much longer, more technical trails.

Insider Tips: “best hiking trails in oahu”

• For the “bridge” section, a slightly easier bypass trail exists on the right
• Go early morning or late afternoon to avoid the intense midday heat
• Bring twice as much water as you think you’ll need—there’s zero shade
• Descending can be harder than ascending—consider using a “sideways” technique and watch your footing
• Stretching before and after is highly recommended to avoid severe muscle soreness

Olomana Three Peaks Trail (First Peak)

Quick Stats: “best hiking trails in oahu”

• Difficulty: Very Difficult
• Length: 4.4 miles round-trip to first peak (full three peaks is 4.5 miles)
• Elevation Gain: 1,600 feet
• Estimated Time: 3-5 hours for first peak only
• Location: Kailua side of the Pali Highway
• Permit Needed: No, limited street parking

The Experience: “best hiking trails in oahu”
The Olomana Trail is considered one of Oahu’s most thrilling and dangerous hikes, featuring near-vertical climbs, narrow ridges, and sections requiring rope assistance. For safety, we strongly recommend going only to the first peak unless you are an experienced hiker with technical skills.

The trail begins innocuously enough on a wide path but quickly steepens into challenging terrain requiring scrambling and using ropes to navigate steep rock faces. The first peak rewards climbers with extraordinary views of the windward side, Kailua, and the majestic Ko’olau mountains. “best hiking trails in oahu”

Why It’s Great for the Adventurous:
Olomana offers legitimate adventure and exposure that most Oahu hikes lack. Even just reaching the first peak gives hikers a taste of more technical mountain climbing without requiring specialized equipment.

SAFETY WARNING:
Several fatalities have occurred on the second and third peaks. We strongly advise against attempting the full three-peak journey unless you are an experienced hiker with technical skills and a high risk tolerance. The first peak offers spectacular views with significantly lower risk. “best hiking trails in oahu”

Insider Tips:

• Never hike this trail alone or in wet conditions
• Wear proper hiking boots with good traction
• Bring gloves for the rope sections to prevent burns and improve grip
• Start early (7:00 AM or earlier) to ensure plenty of daylight for safe return
• Cell service is spotty—tell someone your plans before going

Best Waterfall Hikes

Maunawili Falls Trail

Quick Stats: “best hiking trails in oahu”

• Difficulty: Moderate
• Length: 2.8 miles round-trip
• Elevation Gain: 800 feet
• Estimated Time: 1.5-2.5 hours
• Location: Maunawili, Kailua side
• Permit Needed: No, street parking (NOTE: Trail is undergoing restoration until late 2025)

The Experience:
Note: At the time of writing, this trail is closed for restoration. We’ve included it as it’s expected to reopen with improved facilities in late 2025.

When open, the Maunawili Falls Trail offers a true rainforest adventure culminating at a picturesque waterfall with a swimming hole. The trail traverses muddy terrain through dense tropical vegetation, crosses several small streams, and features roots and rocks that require careful footing. “best hiking trails in oahu”

The falls themselves drop about 15 feet into a deep swimming pool surrounded by mossy rocks—a perfect natural oasis for cooling off after the humid hike in.

Why It’s Great:
This hike delivers the quintessential Hawaiian jungle experience, complete with the reward of a refreshing swim. The terrain is challenging enough to feel adventurous without being technically difficult. “best hiking trails in oahu”

Insider Tips:

• When the trail reopens, check official sources for new parking and access information
• Expect mud regardless of recent weather—wear appropriate footwear
• Bring mosquito repellent and a towel if you plan to swim
• Water shoes are helpful for stream crossings and swimming in the pool

Waimano Falls (Upper Pool)

Quick Stats: “best hiking trails in oahu”

• Difficulty: Moderate to Difficult
• Length: 3 miles round-trip
• Elevation Gain: 800 feet
• Estimated Time: 2-3 hours
• Location: Pearl City, Central Oahu
• Permit Needed: No, street parking

The Experience:
The Waimano Falls Trail offers a less-crowded waterfall experience featuring multiple pools and a small rope swing at the upper pool. The trail descends through strawberry guava forest before reaching the stream and falls, which means you’ll be hiking uphill on the return journey when you’re most tired. “best hiking trails in oahu”

The trail involves several stream crossings and can be extremely muddy and slippery, especially after rain. The effort is rewarded with a series of cascading pools where you can cool off before heading back up.

Why It’s Great: “best hiking trails in oahu”
This hike offers a more secluded waterfall experience than the popular Manoa Falls, with the added bonus of swimming opportunities. The rope swing at the upper pool provides an adrenaline boost for the adventurous.

Insider Tips: “best hiking trails in oahu”

• Save energy for the uphill return journey
• Flash floods are possible—avoid this hike if heavy rain is forecast or occurring
• The rope swing should only be used when water levels are sufficient (usually after recent rainfall)
• Consider bringing a dry bag for electronics as multiple stream crossings are required

Best Coastal Hikes

Ka’ena Point Trail

Quick Stats: “best hiking trails in oahu”

• Difficulty: Easy to Moderate
• Length: 5 miles round-trip
• Elevation Gain: Minimal
• Estimated Time: 2-3 hours
• Location: Northwestern tip of Oahu
• Permit Needed: No, free parking at trailhead

The Experience:
The Ka’ena Point Trail follows the coastline to Oahu’s remote northwestern tip, traversing one of the island’s last stretches of undeveloped coastline. The relatively flat trail follows an old railroad bed along dramatic cliffs where waves crash against black volcanic rock.

The destination is Ka’ena Point Natural Area Reserve, a protected wildlife sanctuary where Hawaiian monk seals frequently rest on the beach and seabirds nest. During winter months (December-April), the offshore waters are prime whale-watching territory.

Why It’s Great:
This hike offers a rare glimpse of undeveloped Oahu and the chance to see protected wildlife in their natural habitat. The trail’s relatively flat terrain makes it accessible, while its length and exposure provide enough challenge to feel accomplished.

Insider Tips:

• There is ZERO shade on this trail—bring sun protection, a hat, and plenty of water
• The trail can be approached from either the north shore (Mokuleia) or west side (Waianae)—the Mokuleia approach is generally preferred
• Enter the protected sanctuary only through the predator-proof fence gates, and be sure to close them behind you
• Keep a respectful distance (at least 150 feet) from resting monk seals

Makapu’u Tidepools

Quick Stats:

• Difficulty: Moderate (due to steep descent)
• Length: 2.5 miles round-trip
• Elevation Gain: 500 feet
• Estimated Time: 2-3 hours
• Location: Eastern tip of Oahu
• Permit Needed: No, free parking at Makapu’u Lighthouse Trail parking

The Experience:
This unofficial but popular trail branches off from the paved Makapu’u Lighthouse path, descending steeply to dramatic tidepools at the ocean’s edge. The descent requires careful footing on loose rock and dirt, but the reward is a series of natural pools carved into the volcanic shelf—some deep enough for jumping and others perfect for soaking while waves crash nearby.

The pools themselves range from calm, protected coves to “toilet bowl” features where surge channels create natural whirlpools. The dramatic setting, with the lighthouse perched on cliffs above and the vast Pacific stretching to the horizon, makes this one of Oahu’s most unique destinations.

SAFETY WARNING:
This area can be EXTREMELY DANGEROUS during high surf or rough ocean conditions. NEVER turn your back on the ocean here, as rogue waves have swept people off the rocks. Check ocean forecasts before attempting this hike, and do not enter the pools if conditions appear dangerous.

Insider Tips:

• The safest conditions typically occur during summer months when south shore surf is minimal
• Wear sturdy shoes for the descent and water shoes or reef walkers for the tidepools
• The unmarked trail branches off approximately 0.75 miles up the lighthouse trail—look for a worn path heading down toward the ocean
• Bring snorkel gear to explore the underwater marine life in the larger pools

Best Sunset Hikes

Tantalus Lookout & Round Top Drive Trails

Quick Stats:

• Difficulty: Easy to Moderate
• Length: Various (0.5-3 miles depending on trail)
• Elevation Gain: 100-500 feet depending on trail
• Estimated Time: 1-2 hours
• Location: Tantalus/Makiki Heights area
• Permit Needed: No, various parking areas depending on specific trail

The Experience:
The Tantalus area offers several interconnected trails with spectacular sunset views over Honolulu, just minutes from downtown. The Tantalus Lookout itself provides a drive-up panorama, but several short hiking trails nearby offer more secluded viewing experiences away from the crowds.

For sunset hikers, we recommend the Kalawahine Trail to Pauoa Flats junction, which provides sweeping views toward the west-facing Waianae mountains that catch the day’s last light in spectacular fashion. The ‘Aihualama Trail also offers beautiful filtered light through the trees as the sun sets.

Why They’re Great for Sunset:
These trails combine accessibility (just 15 minutes from Waikiki) with truly spectacular views, particularly as the setting sun illuminates Honolulu’s skyline with golden light. The relatively short distances mean you can time your hike to reach viewpoints for sunset and still return to your car before full darkness.

Insider Tips:

• For sunset hikes, bring a headlamp for the return journey
• Drive very carefully on Round Top Drive, which has many blind curves
• The temperature drops quickly after sunset in this higher elevation area—bring a light jacket
• For photography enthusiasts, arrive 30-45 minutes before actual sunset to catch the golden hour

Pink Pillbox Hike (Pu’u O Hulu)

Quick Stats:

• Difficulty: Moderate
• Length: 1.6 miles round-trip
• Elevation Gain: 700 feet
• Estimated Time: 1-1.5 hours
• Location: Waianae, west side
• Permit Needed: No, street parking in residential area

The Experience:
Named for the pink-painted military pillbox at its summit (painted in honor of breast cancer awareness), this west-side ridge hike offers arguably the best sunset views on Oahu. The trail climbs moderately but steadily up the steep hillside, with some sections requiring scrambling over rocks.

The summit ridge features several pillboxes, each offering slightly different perspectives on the coastline. The pink pillbox itself frames perfect sunset views over the Waianae Coast, with the sun descending directly into the ocean on clear days.

Why It’s Great for Sunset:
The west-facing location makes this the perfect sunset perch, with unobstructed views of the sun meeting the horizon. The relatively short distance means you can time your arrival perfectly without committing to a lengthy hike.

Insider Tips:

• Allow extra drive time as this trail is far from tourist areas (60-90 minutes from Waikiki)
• Arrive at least 45 minutes before sunset to secure a good viewing spot
• Bring a headlamp or flashlight for the descent
• Be respectful in the residential neighborhood where parking is located
• Continue past the pink pillbox to the final pillbox for even better views and smaller crowds

Essential Oahu Hiking Tips & Safety

Gear Checklist

Essential Items:

• Water (1 liter per hour of hiking in Oahu’s humid climate)
• Sun protection (hat, sunscreen, sunglasses)
• Rain jacket or poncho (weather changes rapidly)
• Appropriate footwear (trail runners or hiking boots depending on terrain)
• Fully charged phone with trail map downloaded offline
• Small first aid kit with blister treatment

Recommended Additions:

• Insect repellent (particularly for valley and forest hikes)
• Trekking poles for steep, muddy descents
• Snacks and electrolyte supplements
• Microfiber towel for waterfall hikes
• Dry bag or waterproof phone case

Weather Considerations

Oahu’s microclimates mean conditions can vary dramatically depending on your location:

• Windward Side (Kailua, Kaneohe): More prone to sudden rain showers
• Leeward Side (Waianae, Ewa): Typically hotter and drier
• Mountain Ridges: Can experience strong winds and quick-forming clouds
• Valleys: Often humid with limited airflow

Always check the weather forecast specifically for the area you plan to hike, not just the general Oahu forecast. The National Weather Service provides location-specific forecasts for different parts of the island.

Safety First

Trail Conditions:

• Recent rainfall can dramatically change trail conditions, transforming easy paths into treacherous mudslides
• Call the Na Ala Hele Trail System at (808) 973-9782 for current trail conditions
• Respect all trail closures, which are typically due to dangerous conditions or ecological restoration

Hiking Partner:

• Solo hiking increases risks—consider joining hiking groups like the Hawaiian Trail and Mountain Club for group excursions
• If hiking alone, always tell someone your planned route and expected return time

Emergency Preparedness:

• Program 911 into your phone—cell service is available on many (but not all) trails
• Know the warning signs of heat exhaustion: dizziness, fatigue, headache, nausea

Water Safety:

• Always check stream conditions before crossing—flash floods can occur with little warning
• Never dive into waterfall pools without checking depth and for submerged objects
• Be extremely cautious around ocean access points, particularly during high surf

Leave No Trace Principles

1. Plan ahead and prepare – Know regulations, pack necessary gear, and prepare for extreme weather, hazards, and emergencies.
2. Travel and camp on durable surfaces – Stay on established trails to minimize impact.
3. Dispose of waste properly – Pack out all trash and leftover food, including pet waste.
4. Leave what you find – Preserve the past and native Hawaiian flora. Leave rocks, plants, and other natural objects as you find them.
5. Minimize campfire impacts – Open fires are prohibited on most Oahu trails.
6. Respect wildlife – Observe from a distance and never feed animals. Keep pets on leash.
7. Be considerate of other visitors – Yield to uphill hikers, keep noise levels down, and respect others’ experience.

Cultural Sensitivity

Many trails pass near or through areas of significant cultural importance to Native Hawaiians. Some guidelines to follow:

• Heiau (temples) and cultural sites: Do not climb on rock structures or remove any items
• Offerings: Respect any offerings you might see on trails (often ti leaves, flowers, or food)
• Private land: Many trails cross private property where access is permitted—respect this privilege
• Photography: Ask permission before photographing cultural practitioners or ceremonies
• Learn: Take time to learn about the cultural significance of the areas you’re hiking

Planning Your Oahu Hiking Adventure

Best Time of Year to Hike on Oahu

While hiking is possible year-round, certain seasons offer advantages:

• April-May and September-October: Ideal shoulder seasons with balanced weather conditions
• June-August: Hottest months but generally drier conditions on most trails
• November-March: Winter brings more rainfall and occasionally stormy conditions, but also the most lush landscapes and active waterfalls

For specific trails:

• Ridge hikes: Best in morning hours year-round to avoid clouds
• Waterfall hikes: Most impressive during winter months or after heavy rain
• Coastal hikes: More comfortable in winter when temperatures are milder

Getting Around

Car Rental: Essential for accessing most trailheads, particularly those outside the Honolulu area. Budget for parking fees at popular trails and consider a high-clearance vehicle for accessing more remote trailheads.

TheBus: Oahu’s public transportation system reaches some trailheads, but service can be infrequent:

• Route 5 accesses Manoa Falls (with a short walk)
• Route 23 passes near the Diamond Head entrance
• Route 20 can get you close to Tantalus trails
