Wellesley, Island State Park is right on the Canadian border. The island is beautiful and the perfect spot to be July to September. They have cabins, RV sites, sites with electric hook up, and rough camp sites. If you love being on the water boat rentals are fairly priced at two locations on the island. The staff was wonderful and eminities were clean and all in working order. They have a nature center that seems to always have interesting adventures for the children. They even have a butterfly sanctuary and plenty of hiking trails.
