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.

Thousand Islands

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.

Thousand Islands Sunset

Every day is beautiful here.

Wellesley Island

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.

Big sites, great fishing!

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!
