Camping near Thousand Island Park, New York places visitors within the St. Lawrence River valley region, where the US-Canada border runs through a waterway dotted with over 1,800 islands. Most campgrounds operate from May through October, with peak season running mid-June through August when water temperatures reach the mid-70s Fahrenheit. Cell service transitions between US and Canadian carriers, sometimes changing unexpectedly while camping on islands close to the border.
What to do
Canoeing on the St. Lawrence: At Wellesley Island State Park Campground, visitors can experience diverse paddling conditions. "We had a wonderful time canoeing, fishing, and spending time together!" writes Trina W., who camped with her child at this park.
Watching international shipping vessels: The St. Lawrence Seaway functions as a major shipping channel with large cargo ships visible from many campsites. "Watch the cargo ships cruise the channel," notes John L. about Wellesley Island, adding that river cruises provide opportunities to view "beautiful islands and homes."
Rock jumping and swimming: Kring Point State Park Campground offers distinctive swimming opportunities beyond typical beach areas. "Kring point has islands as well you can jump off the rocks into the water," explains Christina B., highlighting one of the unique water activities available to campers.
What campers like
Access to both river and bay views: Burnham Point State Park Campground provides varied water frontage. "Beautiful view of the river. Easy access to swim in the water," writes John B., who also appreciated the "plenty of trees to hang your hammock" and the relaxed atmosphere.
Park-specific recreation programs: Cedar Point State Park offers structured activities for families. "One of the few state parks I have been to that offer a staffed rec hall with activities like scavenger hunts, art contests, and ping pong," notes Susan L., who adds that visitors can also "borrow a book, hang a hammock and relax on the river."
Clean facilities despite high usage: Swan Bay Resort maintains well-kept grounds and amenities. "The grounds are spotless, as are the bathrooms and showers. There are several hosts, so help is always available," according to Kathi V., who visited 1000 Islands Campground.
What you should know
Wind conditions affect camping and water activities: River-facing sites experience more significant wind. "Depending on day - EXTREMELY VERY WINDY AND COLD!" cautions Ben B. about Burnham Point State Park, though he notes "the view is beautiful" despite challenging conditions.
Reservation timing is critical: Many waterfront sites book far in advance. "We reserved the site 3 days prior and still found most waterfront campsites already reserved," reports Erin B. at Wellesley Island, who managed to secure Bluejay 3, which was "very spacious and private."
Terrain challenges for tents: 1000 Islands Campground and similar river campgrounds have site limitations. "Lake front campsites are all on a slope - minimum flat space," warns Ben B. about Burnham Point, an important consideration when planning tent placement.
Tips for camping with families
Playground options: Multiple parks have well-maintained play equipment. "The playground was extremely nice!" reports Sara H. about Grass Point State Park, while Courtney M. found Cedar Point's playground "perfect for our kids (8 and younger)."
Swimming areas vary significantly: Each park offers different swimming experiences. "They had a life guard on duty. The beach didn't really have any sand. But had stone steps to walk into the water," Sara H. explains about Grass Point's swimming area.
Wildlife awareness for children: Cedar Point State Park Campground and other parks host diverse wildlife. "Watch out for the skunks and raccoons on this island, they are huge from partaking in campers food!" warns Amanda H., suggesting proper food storage is essential when camping with families.
Tips from RVers
Site selection for connectivity: Reception varies dramatically across campground loops. "Large open sites with not much shade but it is the only loop that gets US Verizon service," notes Bran P. about the Heron Loop at Wellesley Island State Park, important for RVers needing consistent connectivity.
Wind protection measures: Exposed riverfront sites require awning precautions. "My neighbor (who has camped here seasonally for the last four years) mentioned that he lost three awnings to the wind," shares Nancy W. about Swan Bay Resort, suggesting RVers should never leave awnings extended when away from camp.
Water fill locations: Not all sites have direct water hookups. "There are water spigots around the loop to fill up your fresh tank before setting your jacks," explains Bran P. about Wellesley Island State Park's Heron Loop, a helpful logistical detail for RV setup.
