Hawaii offers some of the most diverse and stunning hiking experiences in the world, ranging from easy coastal walks to challenging climbs up volcanic summits. This guide breaks down some of the best trails on each of the major islands, offering actionable tips and real-world insights to help you plan your Hawaiian hiking adventure.

Oahu: Coastal Beauty and Ridge Climbs

Oahu, known as “The Gathering Place,” isn’t just about Waikiki beaches and surfing. It boasts a variety of hikes, from gentle coastal trails to demanding ridge climbs. Let’s explore a few standouts:

Diamond Head Summit Trail

Probably Oahu’s most iconic hike, the Diamond Head Summit Trail is a must-do for any visitor. This 1.6-mile round trip hike takes you to the summit of a 300,000-year-old crater, offering panoramic views of Waikiki and the coastline. The trail is paved and well-maintained, but it does involve some stairs and a short tunnel. According to the Hawaii Department of Land and Natural Resources, the hike takes approximately 1.5 to 2 hours to complete. Note that reservations are now required to enter Diamond Head State Monument, which you can book online here for a nominal fee (currently $5 per vehicle for non-residents and $1 per walk-in). Don’t forget to bring water and sunscreen, as there’s limited shade.

Manoa Falls Trail

For a taste of lush rainforest, head to the Manoa Falls Trail. This 1.6-mile round trip hike takes you through a bamboo forest to a stunning 150-foot waterfall. The trail can be muddy, especially after rain, so wear appropriate footwear. The beauty of this hike is the dense greenery and the feeling of being immersed in a tropical jungle. Note that the trail can sometimes be closed due to landslides, so check conditions before you go. Parking at the trailhead costs a small fee, usually around $5.

Makapu’u Point Lighthouse Trail

This is an easy, paved hike that’s perfect for families and those looking for a scenic coastal walk. The 2-mile round trip Makapu’u Point Lighthouse Trail offers breathtaking views of the coastline, including Rabbit Island and the windward side of Oahu. During whale season (November to May), you might even spot humpback whales breaching offshore. Bring binoculars for a better viewing experience! There’s ample parking, but it can get crowded on weekends. Remember to bring water and sun protection, as there’s very little shade along the trail.

Koko Crater Railway Trail

For a serious workout with rewarding views, try the Koko Crater Railway Trail. This steep climb consists of over 1,000 steps up an old railway track to the top of Koko Crater. Be warned: this hike is challenging! The “steps” are actually wooden ties, and some are uneven and spaced far apart. Bring plenty of water, wear sturdy shoes, and be prepared for a leg-burning workout. However, the panoramic views from the top are well worth the effort. There’s no fee to hike, and parking is free, but arrive early to secure a spot.

Maui: Volcanic Landscapes and Bamboo Forests

Maui, the “Valley Isle,” is known for its stunning beaches and dramatic landscapes, including the Haleakala volcano and the lush Iao Valley. Its hiking trails reflects this diversity:

Haleakala Sliding Sands Trail

Hiking into the Haleakala Crater is an otherworldly experience. The Sliding Sands Trail is a 11.2-mile roundtrip (depending on how far you go) that takes you down into the heart of the volcano. Be prepared for a dramatic change in scenery as you descend into a landscape of volcanic cinder cones and unique plant life. The elevation changes are significant, so take it slow and bring plenty of water. Remember that the weather at the summit can be unpredictable, so dress in layers. Entry to Haleakala National Park costs $30 per vehicle and is valid for 3 days. Advance reservations are required for sunrise viewing at the summit, bookable here.

The Kipahulu District is a separate entrance to Haleakala National Park and is accessed via the Road to Hana. The same $30 park entrance fee applies.

Iao Valley State Monument Trail

For a shorter, easier hike, visit Iao Valley State Monument.

General Hiking Tips for Hawaii

No matter which island you choose to hike on, here are some general tips to keep in mind:

Check the weather forecast before you go.

Hawaiian weather can be unpredictable, and conditions can change quickly, especially at higher elevations.
Wear appropriate clothing and footwear. Dress in layers, as temperatures can fluctuate. Wear sturdy hiking shoes with good traction, especially on uneven terrain.
Bring plenty of water and snacks. Staying hydrated and fueled is essential, especially on longer or more challenging hikes.
Use sunscreen and insect repellent. The Hawaiian sun is strong, and mosquitoes can be pesky, especially in rainforest areas.
Stay on marked trails. Wandering off trail can be dangerous and can damage delicate ecosystems.
Respect the environment and local culture. Pack out everything you pack in, and avoid disturbing the natural environment. Be mindful of cultural sites and practices.
Be aware of potential hazards. These can include flash floods, landslides, falling rocks, and dangerous wildlife (such as wild pigs).
Let someone know your hiking plans. Tell a friend or family member where you’re going and when you expect to be back.
Consider hiring a guide. For more challenging or remote hikes, hiring a local guide can provide valuable expertise and ensure your safety.
