Diamond Head State Monument, Honolulu

One of the first natural landmarks you see as you arrive in Honolulu, Diamond Head State Monument offers several vantage points with views of the entire island. Formed by volcanic eruptions more than 150,000 years ago, this tuff cone covers 141 hectares (350 acres). A well-beaten path leads partway to the top. Lengthy metal and concrete staircases make it easier to traverse the steepest sections, and the very narrow tunnels are illuminated. Climb to the summit if you feel fit, or enjoy the views from the lookouts along the way. Wear comfortable hiking shoes, and bring plenty of water and a snack.
