Wellesley Island State Park Campground

We came to this campground after a week in Algonquin Provincial park in Canada and the contrast couldn't have been greater. Up north we stayed on a large, shady site in a radio free loop and everyone had canoes. In New York we had a cramped, open site and everyone seemed to have a motorboat on a trailer. Our neighbors across the road set up a movie screen . The overall feel was NOT "getting away from it all".
The facilities are good and there's a nice beach and well stocked General store, also a big boat ramp facility with some docks.
We chose this location because we were attending the Antique Boat Show in Clayton, 13 miles away, and this was the closest available. It suited us just fine for that.
Keep your stuff secure, there are brazen raccoons.

We camp with a big rig(40ft) we prefer the heron loop they are very spacious. Nice bathrooms, a small park near the cabins and heron loop, a huge park near the beach and store. They have a beautiful nature center with a lot of kids activities. A ton of trails, they do have full hookup in another loop. By far a beautiful campground and views

This place is top notch. A large park with diverse types of camping. Many tent-suitable sites right on the river are highly coveted so you have to book way in advance. Lots of dry-camping RV sites are easier to book. The full hook-up RV sites are also very difficult to book, but if you score one, it will be a dream experience. Facilities are very well maintained. There’s lots to do…. a swimming beach, boat launches, a Nature Center, hiking trails, and an ADA kayak launch on Eel Bay. Only fifteen minutes to the charming community of Thousand Island Park.

I grew up going to this place with my family so besides it being nostalgic it is absolutely beautiful. The grounds are really taken care of and all the sites are at par. The place offers countless opportunities for just about any activity you could think of. The landscape is gorgeous and just extremely peaceful.

We decided to go the week before Memorial Day. It turned out to be a Canadian holiday weekend so we saw lots of Ontario plates. But by Monday everyone cleared out and we were one of 3 people in our loop (c63) the bathrooms were immaculate (our only complaint was the mens room had no hot water for showers) We kayaked from the ADA kayak launch and had a nice time on Eel bay. We rode our bicycles around and even did rollerblading. So many nice waterfront sites and if you stay in the c loop you have shade, a flat driveway to park on, and electric hookups. All of the other loops that had electric were pretty much wide open with no trees or privacy.

Gorgeous views! We had so much fun! Very quite

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.

We camped in loop F site 43 with full hookups, nice asphalt pad picnic table and fire ring. Our site is located adjacent to a mowed grass path that leads to the main road, close to the camp store. Beautiful area, lots of hiking and biking trails and swim area.

We’ve heard great things about this camp ground and I can see why ppl come here. The views are beautiful, the water is clear, but wow is it crowded! We like to have privacy and prefer a quiet experience but ppl here are packed in. Everywhere we turned there was a person or kid running around on the rocks. Unless we get a hike in tent site I don’t see us ever returning.

This campgrounds is used by my family and friends for years for a fishing tournament.  I don't often attend but I did this year.  The bathrooms didn't look clean at all.  At best, they look like they are cleaned weekly.  The toilet seats looked like they were stained from lack of proper cleaning.  The showers looked grimy as well.

This campground is massive and the park is beautiful.

The state park is really nice, very natural with beautiful views of the St Lawrence River but the beach needs to be cleaned up and the bathrooms are disgusting. There’s one small open field that has full hookups otherwise it’s power only.

NYS may get tons of flack for its politics and politicians. However they're doing it all correct in their state parks. This park is amazing. The views of the ST. LAWRENCE River are amazing. You're around some of the best fishing in the country. We'll. Manicured campground. It's huge by the way. Tons of playgrounds and swimming. Always clean everything. Always friendly staff and campers. Inexpensive I mean really inexpensive. You're 10 min from Alexandria Bay. Boldt castle, singer castle, you can go on river cruises and view these beautiful islands and homes on them. Watch the cargo ships cruise the channel. Electric and water on many sites. Cottages cabins and primitive sites available. Hiking trails all over the park. There's a marina, boat launch and boat rentals. Docking. You can even day trip it use public grills and still enjoy everything the park has to offer. We have so much fun here. It's hard to pack and go home.

Walking areas. Access to water for swimming.

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.

This campground was beyond beautiful and very relaxing.

Lots for everyone to do! New playground, beach, cabins boating full hook ups... they have it all!

My kids loved camping here, great fishing, great sites.

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

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.

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.

The area is incomparably gorgeous with so much to do. I really recommend heading to the nature center and following the trails there. The views are gorgeous and you get some great vistas. There's also fishing, kayaking, that sort of thing. Camp store has fire wood and ice. As for the campsites, I'm used to them being a little more secluded and shaded than the one we stayed at. If you're tent camping and booking through reserve america, I HIGHLY recommend perusing the site map for some time to find a site close to the water and farther from the RV ring. That being said, we loved our time there.

Every day is beautiful here.

LOVELY park. Thousand Islands camping on an island you can drive to...so no boat needed but you’ll regret it if you don’t have one. You can also play golf here, learn at the nature center, and great swimming. Bring what you need since there isn’t much in the way of grocery on the island. Everything pretty clean but it’s so busy in the summer so I don’t fault the caretakers on a few messy stalls. Cool castle, Boldt Castle, to explore too.

One of my favorite places to camp! The sites there are big!!! We usually get 2 sites and place as many as 5 tents between the 2 sites! Watch out for the skunks and raccoons on this island, they are huge from partaking in campers food! The park is very large, you can get in a few miles for a run or bike ride! Great price for camping! There is a boat launch for your own boat or you can rent a boat. The fishing on the St. Lawrence is awesome!!! Catch some perch and have a fish fry back at camp! If you fish near the boat rental there is a place to clean you fish! Perfect place to camp if you want to go to Alexandria Bay! Great shopping and great restaurants! Make sure you visit Bolt Castle! Happy Camping!
