Way down the very end of Moultonborough Neck and immediately to the left of
www.harilla.org you will be very pleased to see a TOTALLY FREE unimproved dirt boat launch area named Harilla's Landing that belongs to the State of New Hampshire, Dept of Transportation that is a "road to public waters".
Looking at the big photo in the above website, it is the waterfront lot of land that is all dirt with no trees that extends out into the water, a wee bit with location, location, location!
