Best Hiking Trails In Oahu HI

Oahu, Hawaii, offers some of the most scenic and diverse hiking trails in the Pacific. From lush rainforests and dramatic ridgelines to coastal paths with sweeping ocean views, the island is a hiker’s paradise. This guide highlights the best hiking trails in Oahu, HI, helping you plan an unforgettable outdoor adventure while optimizing your trip for both safety and enjoyment.

Diamond Head Summit Trail

The Diamond Head Summit Trail is one of Oahu’s most iconic hikes and a must-do for first-time visitors. Located just outside Waikiki, this moderate 1.6-mile round-trip trail leads you up the crater of an extinct volcano. Along the way, you’ll navigate switchbacks, tunnels, and stairs before reaching a lookout that provides panoramic views of Honolulu and the Pacific Ocean. Because it is extremely popular, it is best to start early in the morning to avoid crowds and midday heat.

Manoa Falls Trail

For those seeking a lush rainforest experience, the Manoa Falls Trail is an excellent choice. This relatively easy hike winds through dense tropical foliage, bamboo groves, and towering trees. At the end of the trail, you are rewarded with a picturesque 150-foot waterfall cascading down a rock face. While swimming is not advised due to safety and health concerns, the scenery alone makes the hike worthwhile. Wearing sturdy footwear is essential, as the trail can be muddy and slippery after rain.

Lanikai Pillbox Kaiwa Ridge Trail

The Lanikai Pillbox, also known as the Kaiwa Ridge Trail, offers one of the best sunrise hikes on Oahu. Overlooking the turquoise waters and the Mokulua Islands off Lanikai Beach, this moderate ridge hike is short but can be steep in sections. Old military bunkers, or “pillboxes,” provide unique photo opportunities and viewpoints. To minimize impact on nearby residential areas, park legally and respectfully, and begin your hike well before sunrise for the most dramatic colors in the sky.

Koko Crater Railway Trail

If you are looking for a challenging workout combined with stunning vistas, the Koko Crater Railway Trail delivers. This steep climb follows an old railway line with hundreds of railroad ties acting as makeshift steps. As you ascend, take your time and rest as needed; the trail is demanding but rewarding. At the summit, you’ll enjoy far-reaching views of Hanauma Bay, the southeastern shoreline, and the crater itself. Because there is little shade, bring plenty of water, sunscreen, and a hat.
