Knight Island State Park is a remote 185-acre island campground on Lake Champlain accessible only by boat, offering 1 tent site and 6 rustic lean-to sites with composting outhouses but no potable water. The island features a 2.

5-mile trail system connecting campsites spaced around the shoreline, excellent swimming and fishing opportunities, and requires visitors to arrange their own boat access or water taxi service from nearby launch points at Kill Kare or Knight Point State Parks.

Reservations are required (2-night minimum, up to 11 months in advance), and campers should be prepared to carry all gear as sites are 1/3 to 1 mile from the dock.
