Go if

Private-boat campers and summer paddlers will like the 11 sites, potable water, vault toilets, floating dock, and moorings. Reviews praise the views, trails, and stargazing, but you need to plan transport and pack light.

Skip if

Carry-in access and primitive facilities are the deal-breakers here. There’s no ferry, no showers, no electric hookups, and mosquitoes get heavy at dusk, so anyone wanting easy drive-up camping should pass.
