Tips for Climbing Diamond Head

Diamond Head is one of the most well known and most visited landmarks in Hawaii, and interested visitors can climb to the top of the crater for stunning views. While the trail is open to everyone, however, visitors should take a few steps to prepare for what can be a strenuous hike.

About Diamond Head

Diamond Head, known as Le'ahi to locals, is an inactive tuff cone volcanic crater on the southeastern coast of Oahu, formed approximately 300,000 years ago from solidified ash. The iconic cone got its name from embedded quartz crystals that initially fooled explorers that the cone was composed of black diamond, and despite the inaccuracy, the name stuck.

In the past, Diamond Head was a burial site, and more recently, a military outpost. Today, the crater is a state park with restrooms, a picnic area, and a 1.5-mile round trip trail to the peak. There is a 560-foot elevation gain along the trail, and the summit viewing area offers unparalleled views of Honolulu and Waikiki.

Tips for Your Climb

Climbing Diamond Head is a bucket list item for many visitors to Hawaii, and while demanding, the climb is suitable for most guests. The trail can be steep, however, with stairs in different locations, so climbers should be in reasonable physical condition with good balance and stamina. There is little shade along the trail, and all guests should bring along sunscreen and water. Sturdy, comfortable shoes with good traction and adequate ankle support are a must. The lowest part of the trail is paved and accessible for strollers or wheelchairs, but the climb is not. The steepest part of the climb just before the peak offers a switchback ramp or a staircase to reach the summit; both end at the same spot, and many hikers opt to take the ramp up and the stairs down to get the full experience. Guests with claustrophobia should note that to access the summit, it is necessary to go through a relatively long and very narrow tunnel, with minimal but adequate lighting.

To make your climb as comfortable and easy as possible:

• Budget 1.5-2 hours to complete your climb, depending on your pace, how many breaks you take, and how long you stop for views.
• Begin your climb in the morning when the crater is cooler. The basin's unique geography traps heat and can make afternoon hikes much less pleasant.
• Use the restrooms and refill water bottles at the base of the trail - there are no facilities further up the hike, though there are periodic benches for brief rests.
• Pace yourself to match your ability levels, and watch your footing carefully to avoid stumbles or falls on the sometimes heavily rutted, uneven path.
• Be aware of others on the trail - this is a very popular and crowded hike, with experienced hikers often opting to run, and the narrow trail has little room for passing.
• Be patient at the summit. It will be crowded, but everyone will have an adequate chance for views and photos if desired.

Arranging Your Visit

Diamond Head State Park is open 365 days a year, from 6 a.m. to 6 p.m., and the last entrance to the climb is at 4:30 p.m. Admission to the park is $5 per car or $1 per pedestrian (cash only), and parking is ample. Pets other than service animals are not permitted.

Whether you choose to visit Diamond Head on your own or with an organized tour group, climbing to the crater's peak is a once in a lifetime experience that no Hawaiian vacation should be without.
