14 Reviews of Wellesley Island State Park
D10 and friends

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.

Nice park

Walking areas. Access to water for swimming.

Not at all impressed

I give it a 1 star because the lady at check in was wonderful. Great to work with. Otherwise the park isn’t worth any stars. The sites are tight and difficult to back in if someone is across the road. The bathroom/shower building was filthy and smelled horrible. Also the park is so spread out you have to drive to get to anywhere. I would recommend to not waste your time or money on this park.

First trip of the season!

We arrived to Wellesley Island State Park Friday May 24, 2019. The entrance to the park was very clean and well kept. The office staff were very friendly! We stayed in the Heron(H) loop. The sites were beautiful with a lot of yard or grass space. The bathrooms/showers were clean and private. There was a playground only a few sites down from us which was great for entertaining our little one. Soon after we finished setting up we drove over to the Park store. It was very easy to find. There was a large playground, beach, arcade, laundry, and marina in the same area as the store. The staff in the store were very helpful and they had many things to offer. From camp tools to ice cream and toys. Unfortunately it rained all day Saturday so when we woke up we had some mud and standing water on our site. The staff were amazing and moved us to a site that was even more beautiful and dry. Luckily Sunday was sunny so we got to enjoy the whole day outside on our new site. Overall our camping experience at Wellesley Island State Park was great! It was clean and spacious and, the staff was great. We had a great Memorial Day weekend!

Beautiful park

We camped here with one of our children, and had a wonderful time canoeing, fishing, and spending time together!

Large NY State Park!

Large NY State Park (7 loops) on the St Lawrence River in the Thousand Islands area of NY. All roads are paved with grass and gravel sites. We were on site H33 in the Heron Loop with 30A electric. There are water spigots around the loop to fill up your fresh tank before setting your jacks. Large open sites with not much shade but it is the only loop that gets US Verizon service. Marina on site along with a nice Nature Center and miles of hiking trails by the water. Nice place to ride your bike with a few hills.

1000 Islands

This is on the same island as Boldt Castle. You need to pay a toll to get to the island. It’s big enough that you can forget you’re on an island. The sunsets are great and there’s a lot to do on the water, including a nice beach. There are a ton of camp sites, many along the water, but they do fill up in summer. Most of them are partially shady. It’s very buggy here but so is all of NY in the summer.
