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

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.
