1. Diamond Head State Monument
Diamond Head is volcanic tuff cone located on the eastern side of Waikiki’s coastline. About 300,000 years ago, a single, explosive volcanic eruption sent a huge amount of ash and particles into the air. As those particles and ash settled, they cemented together into a kind of rock, tuff, forming the crater’s rim. You can witness the crater while you hike on the trail to the summit of Diamond Head. The historic trail to the summit was built in 1908 as part of O’ahu’s coastal defense system. It is a 0.8-mile hike from trailhead to the summit, approximately 30 minutes to get to the top.
Diamond Head State Monument is open all year long, from 6 a.m. to 6 p.m., including holidays. The latest time you can enter to hike the trails is 4:30 p.m. Cash is required to buy tickets; $5 per car or $1 per pedestrian.

The water in the Bay is crystal clear and glistening with iridescent colors from green to blue, calm, and shallow with numerous fish and beautiful corals that you can easily see. Hanauma Bay is one of the best spots on O’ahu for snorkeling and swimming, and the crescent white sand beach is prefect for sunbathing.
