Waquoit Bay NERR Campground offers primitive camping on Washburn Island, accessible only by private boat, with 9 family sites and 1 group site featuring composting toilets but no fresh water, electricity, or showers—campers must bring their own water and practice carry-in/carry-out.

Camping costs $8/night for Massachusetts residents and $20/night for non-residents, with reservations required at least 24 hours in advance through ReserveAmerica.

The island provides excellent opportunities for fishing, kayaking, and hiking through oak and pine forests and coastal salt ponds, though visitors should be prepared for variable boating conditions and check themselves for ticks.
