About this home

Cute camp in a protected area on Rattlesnake Island, a great location on the south side of the peninsula. Bright natural light glistens across the waters of the "Big Lake" and cascades onto the large deck and into the living space. Amazing covered boat docking for multiple boats, you will love not having to run out in a rains storm to cover your boat! Level lot with walk-in sandy swimming or jump off the dock and swim to the raft. Protected from the prevailing winds from the north west so great for swimming, kayaking and easy boat docking. The camp has an open floor plan, 3 sleeping areas, laundry and 2 baths. Rattlesnake is just a quick trip from several close marinas and has a great trail system on the Island for a hike. Discover island life and you will never want to leave!!
