Traveling to Three Mile Bay by RV

Three Mile Bay sits along State Route 12E, approximately 15 miles northeast of Watertown via Routes 37 and 12E. The most direct approach for RVers is taking I-81 to Exit 50 (Route 37), then following Route 37 east to Route 12E north. This route avoids the tighter downtown areas and provides better clearance for larger rigs.

Route 12E itself is RV-friendly with adequate shoulder space and good sight lines, though it does wind along the shoreline with some moderate curves. There aren't any significant bridge restrictions or weight limits to worry about between Watertown and Three Mile Bay. The road surface is generally well-maintained, though winter conditions can create challenges with lake-effect snow.

Overnight parking options are limited in the immediate area. Walmart parking isn't available since there's no store nearby, and most roadside areas are too narrow for safe overnight stays. Your best bet for overnight parking is to plan ahead and book a spot at one of the area campgrounds or continue to a larger town with more services.
