Camp Bentzon Kawau Island is a camp on 28 acres of bush at North Cove, Kawau Island, in the Hauraki Gulf, with a Google rating of 4.8 from 103 reviews. The website describes an outdoor camp for young people and family groups, reached by road to Sandspit and then a short ferry ride.
The website says kayaks, sailing boats and paddleboards are included, along with a confidence course, a fitness trail, bush walks, fishing and wharf jumping. These activities are covered by the nightly charge. The camp has 110 beds, a separate 10-bed unit with wheelchair access and a commercial kitchen. Guests manage their own activities, because no camp staff oversee them, so they need to bring the skills to use the equipment. Weekdays are for school camps, and weekends host family groups and clubs.
For a self-managed camp escape on Kawau Island, it is a highly rated place worth planning the ferry for.
