Knight Island State Park, Vermont

Don’t trustingly put Knight Island State Park into the GPS and start driving--you'll end up swimming with the fish. This 185-acre island is located 2 miles east of North Hero, Vermont in the northern end of Lake Champlain’s “inland sea,” and is only accessibly by boat. Bring your own vessel or arrange for a water taxi (unfortunately not on Uber yet, but you can call Driftwood Tours for a ride). Be warned that there are no docks on the island, so beaching or anchoring off-shore are your only options.

This is a trip for naturists who are ok with being at the whim of the Lake Champlain’s forces. This off-the-grid location is rumored to be a contender for the next “Survivor” destination (but you didn’t hear it from us!).
