One of the most popular hiking trails on Oahu is the Diamond Head Hike. Located on the southeastern coast of the island, Diamond Head is a volcanic crater that offers stunning views.

The trail is relatively easy, but the last section includes a steep climb up a series of switchbacks and a narrow spiral staircase. It’s not recommended for those with mobility issues.

Another great hiking spot is the Makapuu Lighthouse Trail. This trail is located on the easternmost point of the island and offers panoramic views of the ocean and neighboring islands. The hike is just over two miles and takes about 1-2 hours roundtrip. The trail is paved and relatively easy, but can be hot and sunny, so it’s important to bring plenty of water and sunscreen.

Physically Demanding Hikes

For those looking for a more challenging hike, the Koko Crater Railway Trail is a must-see. This hike takes you up the steep side of an old military tramway that was used during World War II. The trail is just under a mile, but includes over 1,000 steps to reach the top. The climb can be strenuous, but the views at the top are well worth the effort.

If you’re looking for a hike that takes you through lush rainforest, the Manoa Falls Trail is the perfect choice. This trail is located just outside of Honolulu and takes you on a one-mile hike through a verdant rainforest to a stunning waterfall. The trail can be muddy and slippery, so it’s important to wear sturdy shoes and use caution. Additionally, be sure to bring insect repellent as the rainforest can be a breeding ground for mosquitoes.

Unique and Off the Beaten Path

For those seeking an off-the-beaten-path hiking experience, the Aiea Loop Trail offers a less crowded and more secluded hike. Ideally located, it’s found the hills above Pearl Harbor. This hike takes you on a 4.8-mile loop through lush tropical forest and offers stunning views of the island’s interior. The trail is rated as moderate and can take 2-3 hours to complete, but the solitude and natural beauty of the area make it well worth the effort.

When hiking on Oahu, it’s important to take proper precautions and be prepared. Hawaii’s climate can be unpredictable, and weather conditions can change quickly. Always bring plenty of water, sunscreen, insect repellent, and snacks, and wear appropriate clothing and footwear. Additionally, be sure to follow all posted signs and stay on designated trails to avoid damaging delicate ecosystems and preserve the natural beauty of the island.

Tourism is Ruining the Island Hiking Experience

One important note for hikers on Oahu is to be mindful of the impact of tourism on the island’s delicate ecosystems.
