Wellesley Island State Park Parking

There will be no parking allowed at the H Area boat launch or along the roadsides due to construction. Parking for ice fishing is allowed at the dump station, at the Nature Center parking lot and the marina parking lot. We apologize for the inconvenience but it should only be for this winter.

Pet Policy

A maximum of two pets are allowed in campsites and day use areas unless prohibited by sign or directive. Pets are to be supervised at all times and either be crated or on a leash not more than 6-feet in length. Proof of rabies inoculation shall be produced if requested by staff. Pets are not permitted in playgrounds, buildings, golf courses, boardwalks, pools and spray-grounds or guarded beaches (this does not apply to service animals).

Wellesley Island State Park is the largest camping complex in the Thousand Islands region with 432 campsites. Within this rustic paradise, fishing is excellent--particularly for perch, smallmouth bass, pike, and muskie. To accommodate boaters, the park has a full-service marina and four boat launches. A sandy beach on the river offers great swimming and sunbathing and there is a Camp Store, Laundromat, Arcade and the 9-hole Wellesley Island State Park Golf Course on the Island.

One of the main attractions of the park is the Minna Anthony Common Nature Center, which includes educational displays, gift shop, varied habitats such as wooded wetlands, 3 miles of shoreline and open granite outcrops, and miles of trails for hiking, cross-country skiing and snowshoeing. The Nature Center provides educational and recreational programs for all ages. One special feature at the nature center is the 1/4-mile accessible trail that includes access to picnic tables and the seasonal butterfly house. In July and August, a 16 passenger Voyageur Canoe program leaves the docks of the nature center, touring Eel Bay.

For the less rugged camper, there are 56 campsites in the Fox loop that offer full hook-up. There are also regular tent/trailer sites with electrical hook-ups, a cabin colony, facilities for group camping and twelve vacation rentals, which will enable you to enjoy the sunset from the porch of a fully outfitted cottage. You can choose a two- or three-bedroom cottage with all the comforts of home, including a bathroom with shower, kitchen with refrigerator and stove, bedding, cooking utensils, dishes, glassware, silverware, etc. Outside each vacation rental, a picnic table and ground grill are provided for meals and evening campfires.

Pavilion Information
Wellesley Island has one pavilion. The day use price is $100 and can accommodate up to 100 people. Check availability at

Highlights of Wellesley Island State Park:

  • Wellesley Island State Park has the largest camping complex in the Thousand Islands, which includes wilderness campsites that can only be accessed by foot or boat.
  • The Minna Anthony Common Nature Center has nine miles of hiking trails, and 5 miles of cross country ski and snow shoe trails. The nature center is open year round. During the winter months you can visit the fire place to warm up and visit with other explorers. The trails have a diversity of habitat: field, forest, wetlands and views of the Saint Lawrence River.
  • Take a trip in our 36 foot long Voyageur Canoe! The canoe travels along the water's edge for a 3 mile paddle while a naturalist points out geological features that make up the Thousand Islands. Voyages are in July and August.
  • Wellesley Island, the island Wellesley Island State Park resides on, has an internal body of water called the Lake of the Isles, which nearly doubles the island's waterfront.
  • Bald eagles can be spotted in the park.
  • Use of Wellesley Island began in 1898, when there was a small settlement and the primary use of the land included crop and dairy farming, and grazing of cattle and sheep. It became a state park in the 1950's when the owner gave the land to the park commission.
  • Located in the St. Lawrence River corridor, the natural areas of the park are primarily forest communities and open wetland complexes.
  • There are 18 different natural community types within the park, 3 of which are considered significant ecological communities and take up almost half of the acres of community types in the park.

Everyone is a Steward: Be a Wellesley Island State Park Hero!

  • Know the rules and concerns for the area you'll be visiting.
  • Leave all natural objects as you find them.
  • Let nature's sounds prevail. Avoid loud voices and noises.
  • Respect other visitors and protect the quality of their experience. Be courteous. Yield to other users on the trail.
  • Observe wildlife from a distance. Do not follow or approach them. Never feed animals. Feeding wildlife damages their health, alters natural behaviors, and exposes them to predators and other dangers.
  • Use extra caution when using headphones. You may not be able to hear warnings.
  • Don't litter.
  • Hike and camp on established, durable trails and campsites.
  • Be careful with your fire.

Ask a Naturalist!

Q: What kind of fish are in the St. Lawrence River?

A: If you fish in the St. Lawrence River, you may catch smallmouth and largemouth bass, northern pike, walleye, yellow perch, bullheads or various types of panfish.

Q: What is suitable clothing for the trails?

A: Sneakers, or boots, are appropriate for footwear - no flip flops or high heels. Long pants will protect your legs, and bug spray will help avoid bug bites.

Q: Can strollers be used on the trails?

A: It is not recommended to use strollers on the trails. Most trails are rugged with roots and rocks that stick up. It is recommended to have a back pack for your child.

Q: Can dogs walk on the trails?

A: Yes, as long as they are on a six foot leash and have proof of rabies vaccination.

Q: How do I avoid poison ivy?

A: In order to avoid Poison Ivy, one needs to know what it looks like. If you're not familiar with it, Google it, download a picture and print it out so you can carry it with you. You can catch poison ivy from any part of the plant, so learn how to identify leaves and vines. Poison Ivy is very common and grows throughout the preserve on trees and on the ground. To be on the safe side, don't brush up against or touch vegetation you're not familiar with. If you think you have come in contact with poison ivy, wash that area thoroughly with a product like Technu, which washes the poison ivy oils away.

Q: What should I do if I see a male deer with antlers?

A: Usually deer are more afraid of us than we are them. However, if it's the rutting season, male deer can be more aggressive and territorial because they're vying for mating privileges with does. Don't panic. Stop. Slowly back away and if possible, return the same way you came. If the deer snorts and starts toward you, get behind the largest tree you can and summon help as soon as possible.

Did You Know?

- DID YOU KNOW? You can tell a male and female monarch butterfly apart by looking at the hind wing. If there is a bulb on the back of the hind wing, the butterfly is a male. You can get a closer look at the monarch butterfly at our seasonal Butterfly House. The house is open July and August.

- CHECK IT OUT! Beavers have forever-growing teeth. They need their teeth to continuously grow to be able to gnaw and chew trees. They use trees to build homes (lodges), build dams, and gather food. Beaver activity can be found in east trail wetlands.


  • Archery hunting, in designated areas, by permit only. Beginning October 1st. Please contact the park for more information.

Did You Know? If a monarch has a bulb on it's hind wing, it's a male butterfly. No bulb means it's a female.
