One of Hawaii’s most recognizable landmarks, Diamond Head (Hawaiian name: Le’ahi) is located on Oahu’s southeastern coast. Diamond Head Hike is one of the best things to do in Hawaii and here’s everything you need to know to enjoy it!

The saucer-shaped crater was formed during a volcanic eruption 300,000 years ago. The trail starts at the crater floor. The hike takes about an hour for a fit individual. In 1908 the .8 mile trail to the summit was built as part of Oahu’s coastal defense system.

Trail Information

The Diamond Head Crater Trail is a 1.6-mile out-and-back hike that starts at the Diamond Head State Monument parking lot. The trail begins as a paved walkway, but soon transitions to a dirt and rock path that winds its way up the crater’s outer slopes. The hike includes steep stairs, uneven terrain, and two tunnels, including a 225-foot lighted tunnel. The summit of Diamond Head, which comes after a 560-foot ascent, offers panoramic views of Waikiki Beach, Honolulu, and the surrounding ocean.

Overview

The Diamond Head Crater Trail is one of Hawaii’s most iconic and popular hiking trails, attracting millions of visitors each year. Located on the island of Oahu, the trail offers breathtaking views of Waikiki Beach, the Pacific Ocean, and the surrounding landscape. The trail is moderately difficult, with a 560-foot elevation gain, and takes approximately 1-2 hours to complete. The hike is a must-do activity for tourists visiting Honolulu, offering a glimpse into the island’s rich history, geology, and natural beauty.

Park hours are 6 am-6 pm and the last entry to hike the trail is 4 pm. Open daily except for Christmas and New Year.

Tips and Precautions

Hikers should wear comfortable walking or athletic shoes, sunscreen, and a hat, and bring water and snacks or a small lunch. A light jacket may be needed in case of strong winds or rain showers. Visitors should remain on the marked trail to avoid erosion and loose rocks, and pets are not allowed in the state park, except for service animals. The trail can be congested, especially during peak hours, so visitors are encouraged to arrive early or consider visiting during the off-season.

Allow 1- 2 hours for the hike. I suggest starting as early in the day as you can get a reservation to enjoy early morning views like this of Waikiki. It’ll also be less hot and less crowded!

Diamond Head Hike is not as strenuous as Koko Crater Trail, but the payoff is equally stunning!
