Introduction
Oahu has some of the best hikes in Hawaii, ranging from short waterfall walks near Honolulu to exposed ridge trails on the windward coast. Whether the goal is a sunrise over the Mokulua Islands, a jungle waterfall or a volcanic crater climb, most of the island’s popular trails can be reached within 30 to 45 minutes of Waikiki.
For most visitors, a mix of one waterfall hike, one sunrise hike and one Honolulu crater trail gives the strongest first-trip experience.
This guide covers the best hikes in Oahu organised by type — waterfalls, Honolulu trails, sunrise routes, Kailua area hikes and short walks — along with practical details on distance, difficulty, gear and common mistakes to avoid.

Best Waterfall Hikes in Oahu
Waterfall hikes are among the most searched hikes in Oahu, and for good reason. The island’s wet valleys create accessible falls within a short drive of Honolulu. Below are four of the best waterfall hikes in Oahu, Hawaii.
Manoa Falls
- Distance: approximately 2.6 km round trip
- Difficulty: easy to moderate
- Trailhead: Manoa Falls Trailhead, end of Manoa Road
Manoa Falls is the most popular waterfall hike in Oahu and one of the easiest to reach from Waikiki. The trail passes through a dense rainforest canopy and ends at a roughly 45-metre waterfall. The path is often muddy, so closed-toe shoes with grip are essential. Swimming at the base is generally discouraged due to the risk of leptospirosis in the standing water. Hiking in Oahu to Manoa Falls usually takes about 45 minutes to one hour each way.
Lulumahu Falls
- Distance: approximately 2.4 km round trip
- Difficulty: moderate
- Trailhead: Near the Old Pali Road, Nuuanu area
Lulumahu Falls is less crowded than Manoa Falls but requires more route-finding. The trail crosses a stream several times and can be slippery after rain. A permit from the Hawaii Board of Water Supply may be required. The reward is a tall, secluded waterfall surrounded by dense jungle.
Waimea Falls
- Distance: approximately 2.0 km round trip
- Difficulty: easy (paved path)
- Location: Waimea Valley, North Shore
Waimea Falls is one of the few hikes on Oahu with waterfalls where swimming is usually permitted. The paved botanical garden path makes it accessible for families and visitors of all fitness levels. There is an entry fee to Waimea Valley. Lifeguards are typically present at the falls.
Likeke Falls
- Distance: approximately 1.6 km round trip
- Difficulty: easy
- Trailhead: Near the H3 freeway overpass, Kaneohe side
Likeke Falls is a short, relatively flat walk that ends at a small but photogenic waterfall. It is a good option for visitors who want a quick waterfall experience without a strenuous hike. The trail can be muddy and unmarked in places.
Hikes in Honolulu, Hawaii
The most convenient hikes in Honolulu, Hawaii are the two volcanic crater trails — Diamond Head and Koko Head — plus the coastal walk to Makapu’u Lighthouse. All three double as volcano hikes in Oahu because they follow the remains of ancient volcanic formations along the island’s southeast coast.
Diamond Head (Le’ahi)
- Distance: approximately 2.6 km round trip
- Difficulty: moderate (steep stairs near the summit)
- Trailhead: Diamond Head State Monument, inside the crater
Diamond Head is the most recognisable hike in Honolulu. The trail climbs from the crater floor through tunnels and steep staircases to a summit with 360-degree views of Waikiki, the Pacific and the Koolau Range. A reservation and entry fee are now required through the Hawaii DLNR online booking system. Book in advance — walk-up availability is not guaranteed.
Koko Head Stairs
- Distance: approximately 2.8 km round trip
- Difficulty: hard (1,048 railway-tie steps)
- Trailhead: Koko Head District Park, east Honolulu
Koko Head is a steep, straight climb up an old military railway incline. The trail is exposed to the sun with no shade, so early morning is strongly recommended. The summit offers views across Hanauma Bay and the southeast coast. This is not suitable for those uncomfortable with heights or steep, uneven steps.
Makapu’u Lighthouse Trail
- Distance: approximately 3.2 km round trip
- Difficulty: easy (paved)
- Trailhead: Makapu’u Lookout parking area, east Oahu
Makapu’u Lighthouse Trail is a wide, paved path with ocean views the entire way. It is one of the most family-friendly hikes in Honolulu. During winter months, the trail is a popular spot for whale watching. The lighthouse viewpoint also overlooks Rabbit Island and Makapu’u Beach.
Sunrise Hikes in Oahu
Oahu’s east-facing ridges and coastal trails make it one of the best islands in Hawaii for sunrise hikes. The following trails are popular for early-morning starts.
Lanikai Pillbox (Kaiwa Ridge Trail)
Lanikai Pillbox is widely considered the best sunrise hike in Oahu. The short but steep trail reaches two old military pillboxes with unobstructed views over Lanikai Beach and the Mokulua Islands. Arrive before dawn and bring a headlamp for the initial climb in the dark. The trail is in Kailua, approximately 30 minutes from Waikiki.
Makapu’u Lighthouse Trail
Makapu’u also works well for sunrise because the paved trail is safe to walk in low light and the viewpoint faces east. It is an easier alternative to Lanikai Pillbox for those who prefer a gentler path.
Diamond Head
Diamond Head opens early enough for visitors to catch the first light from the summit. Check the current opening time through the Hawaii DLNR reservation system, as hours may change by season.
Hikes in Kailua, Oahu
The Kailua and Windward Coast area offers several hikes in Oahu ranging from easy ridge walks to advanced scrambles.
Lanikai Pillbox (Kaiwa Ridge Trail)
Covered above under sunrise hikes. Approximately 2.8 km round trip with moderate difficulty. Popular for sunrise but worth visiting at any time of day for the views.
Olomana Three Peaks
- Distance: approximately 7.4 km round trip (first peak only is shorter)
- Difficulty: hard to extreme (exposed ridgeline, rope-assisted sections)
Olomana is one of the most challenging hikes in Oahu. The first peak is achievable for fit hikers, but the second and third peaks involve narrow, exposed ridges with serious fall risk. This trail should not be attempted in wet conditions. It is not recommended for beginners or those uncomfortable with heights. Multiple fatalities have been recorded on this trail.
Ka’au Crater
- Distance: approximately 5.6 km round trip
- Difficulty: hard (steep, muddy, rope-assisted sections)
Ka’au Crater passes several small waterfalls before reaching the rim of an old volcanic crater. The trail is steep, often muddy and involves scrambling over rocks and roots. It is best suited for experienced hikers.
Short Hikes in Oahu
Not every hike in Oahu requires a full morning. The following short hikes in Oahu are under 3.2 km round trip and suitable for beginners or families with children.
- Makapu’u Lighthouse Trail — approximately 3.2 km, paved, easy. Ideal for families and whale watching in winter.
- Likeke Falls — approximately 1.6 km, flat, easy. Quick waterfall walk near Kaneohe.
- Waimea Falls — approximately 2.0 km, paved botanical path, easy. Swimmable waterfall on the North Shore.
- Manoa Falls — approximately 2.6 km, easy to moderate. The most accessible rainforest waterfall near Honolulu.
Oahu Stairs Hike: What You Need to Know
The Haiku Stairs, commonly known as the Stairway to Heaven, are one of the most searched hikes in Oahu. However, the stairs have been closed to the public since 1987 and accessing them is illegal. The Honolulu City Council voted to remove the stairs in 2021, and demolition work began in April 2024, but court injunctions have repeatedly halted the process. As of mid-2025, the stairs are still physically standing but the site is fenced, monitored by security and subject to ongoing litigation.
Trespassing carries fines reported at approximately USD 1,000, and police presence near the site has increased. Do not plan a trip around hiking the Haiku Stairs. The area is an active legal dispute zone and conditions on the partially dismantled structure are dangerous.
Hikers looking for a similar steep-staircase experience should consider Koko Head Stairs, which offers a comparable physical challenge with legal access and open ocean views.
What to Bring on an Oahu Hike
Oahu’s trails range from paved coastal paths to muddy jungle routes. Pack according to the trail, but the following items are useful for most hikes in Oahu.
- Closed-toe hiking shoes or trail runners with grip
- At least one litre of water per person
- Sun protection: hat, sunscreen, sunglasses
- Light rain jacket or shell (rain can arrive quickly in the valleys)

Common Mistakes to Avoid
- Not booking a Diamond Head reservation in advance and being turned away at the gate
- Wearing flip-flops or sandals on muddy trails like Manoa Falls or Lulumahu Falls

- Starting Koko Head after 9 AM when the trail is fully exposed to the sun
- Not carrying enough water on exposed trails like Koko Head and Makapu’u
- Attempting to hike the Haiku Stairs — the site is closed, illegal to access and carries fines of approximately USD 1,000
- Parking illegally at trailheads in residential areas and receiving a citation
- Skipping the offline trail map — mobile signal is weak or absent on many Oahu trails
