About this home

Location, location, location! Located on the sunny side and only 20' from water's edge this cabin is priced town assessed value! Flat lot with deep water seasonal dock and out of the prevailing winds. Rehab the existing cabin or build within the footprint. .. This has been owned by the same family since 1969. There is a Vermont Castings woodstove for those chilly nights and the roof is newer. Stop and smell the roses. .. this is a great starter cabin! Rattlesnake Island is an association island with a mainland pick up dock, boat ramp and parking area. There are great hiking trails to the top of the island where the view is spectacular!
