Ellacoya State Park is located in Gilford on the southwest shore of Lake Winnipesaukee, New Hampshire’s largest lake. The 600-foot long sandy beach, with views across the lake to the Sandwich and Ossipee mountains, is a great place to spend with the family for a full day of swimming and picnicking. The campground includes 37 sites available by reservation only, and offers three-way hook-ups. Tents are not allowed at the RV park. Pets are not allowed in the RV campground or in other areas of the park.
