Another large, well maintained and facilitated campground. At least 200 sites with spaces for tents and RVs with electric. Reasonably spread out, some sites are relatively isolated and give the feeling of being in nature and in the woods/by the water while others are more or less in a field. I found the perfect site D10 tucked away at the end of a short driveway directly on the water with a little walk out to a small rocky outcropping perfect for catching the sunset or watching the boats and day go by. Bathrooms were decent and reasonably places, never being too far from anyway. Plenty of water was available throughout. The entire island itself is an interesting area and can be explored by bike to make for a great day of site seeing and local immersion. Alexandria Bay is not far away too and is essentially the only civilization you’ll find around, with plenty of bars restaurants and shops, as well as boat tours around the thousand islands are and to the Boldt Castle. The Boldt castle is an awesome adventure. For about $20 you get a boat ride over and can spend as little or as much time as you want on the island exploring the grounds and the buildings. The history of the building and in the building gives pretty good insight and background to what is and is on Wellesley Island, where you are staying.
