Wellesley Island State Park has the largest camping complex in the Thousand Islands region. Within this rustic paradise, fishing is excellent--particularly for smallmouth bass, pike, and muskie. To accommodate boaters, the park has a full service marina and three boat launches. A sandy beach on the river offers great swimming and sunbathing and there is a recreation barn 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 a museum, varied habitats such as wooded wetlands, 3 miles of shoreline and open granite outcrops, and miles of trails for hiking, cross-country skiing and nature education. 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 regular tent/trailer sites and a cabin colony, including 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.

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.
Interested in hunting for frogs or looking through mud for the funny looking macroinvertebrates that call the sediment at the bottom of a pond home? Then join us at the pond at 1 pm on Friday, July 29th with dip nets and seine nets to look for the critters that call our pond home. Hike North at 2 pm and look for the bugs and salamanders that thrive in the damp environments under rocks and rotting logs.
Owls are fascinating birds. Come dissect owl pellets at 1 pm on Saturday, July 30th to see what owls eat. There is a $1 fee for this program to help cover the cost of the owl pellets. Stay until 2 pm on Saturday, July 30th and you can make a clay garden snail to take home with you then join us around the campfire from 6-8 pm for S'mores and more!
