Diamond Head (Le'ahi) Summit Trail is a 1.6 mile heavily trafficked out and back trail located near Honolulu, HI that offers scenic views and is good for all skill levels. The trail is primarily used for hiking, walking, and trail running and is accessible year-round.
The Diamond Head Summit trail hike is likely the most popular hike in Oahu, and for good reason. While fairly steep, this easy hike starts from the middle of the Diamond Head volcano crater and climbs about 500 feet up the side to the top of the rim. The Diamond Head crater is more than 3,500 feet in diameter and is part of the Hawaiian volcano chain from more than a half million years ago (don't worry, it has been dormant for at least 150,000 years now). The crater is also called "Le'ahi," which means "brow of the tuna" in Hawaiian. It got the name Diamond Head almost 200 years ago when British sailors believed there were diamonds in the side of the crater. Although none were found, the name stuck. The trail was built in 1908 as part of the Oahu coastal defense system. The World War II bunkers on top now support antennas used by the government. The trail starts on a paved path before climbing several steep switchbacks leading to the first set of stairs. After the stairs you will climb through a tunnel and then climb up another set of stairs before reaching the bunkers at the top of the rim. Once on top you can climb up to the top of the bunkers for 360-degree views of the island, with Waikiki not too far away.
It is not an easy trail going up after the pavement ends and many hikers on the day we went were not prepared for the rough pathway at the switch backs. The bonus is the view!
Seemed a bit difficult for an easy, after the pavement it is a good climb. Had fun and got to see a beautiful view.
Nice trail to a beautiful view at the top. Not too intense, but definitely wear sneakers. Dry and a clear path. Lots of people during the afternoon but overall nice path.
Really great trail, my husband, daughter(9) and myself enjoyed the views and breeze once we got to the top. Stairs were the worst part, the rest was enjoyable! Very crowded, parking lot is small so you have to wait in line for cars to leave.
Awesome views--though it gets very crowded--so go early. Otherwise, you'll think you're in line at Disney.
Good trail ... Lots of good views ... Bring plenty of water !!!
Great view! Yet another hike I didn't bring enough water on. (I never seem to learn!) the best part waste shave ice after completing! :-)
Great view. Easy trail. Better to do it early in the morning. I did it at 2pm and it was so hot.
Listen, there's a guy up top frequently who tries to sell hiking certificates at a suggested "donation" rate of $10-15. He does not work for the park and is not an official vendor. You can get your official certificate at the entrance, in the gift shop for much cheaper ($2.50).
Well worth the trip up; went Christmas day 2015 with the family and lucked out with parking. The place was packed!
Get there early before the parking lot gets full. There's $5 cash only fee for parking. The hike was really easy but the view is spectacular.
