Coral Crater Adventure Park opened in January 2017 as Hawaii's only full-service adventure park, offering a groundbreaking range of new family-friendly, group, and individual outdoor activities in West Oahu. This 35-acre park has transformed a former U.S. Navy coral quarry into two multi-use areas: a 10-acre crater for aerial and terrestrial forest adventures, and a 6,000-square-foot lawn, observation deck and landscaped picnic area ideal for team-building gatherings, group activities, celebrations, and family events.
