Formed over 300,000 years ago, Diamond Head Crater's history and natural beauty make it a fascinating site for visitors.

Along the historic trail, you'll encounter tunnels and steep switchbacks, and plenty of stairs! Don't forget to bring water.

But the family-friendly trail is well worth the effort! From the summit, you'll find panoramic views of the Pacific Ocean and Honolulu.

Reservations are mandatory & open 30 days in advance online. They fill up quickly!  But don't worry...
