Floating Battery Island is a primitive boat-in campsite consisting of two islands with 15 total campsites (11 on the larger island, 4 on the smaller) in Lake George's Narrows, accessible only by power boat or paddle craft.

Each site includes a dock for one boat, fireplace, picnic table, and pit toilet, making it ideal for paddlers and anglers seeking a remote island camping experience.

Note that all supplies must be brought in advance, pets are prohibited, and advance reservations (up to 9 months ahead) are strongly recommended.
