About this park

Wellesley Island State Park has the largest camping complex in the Thousand Islands region. Secluded wilderness sites nestled along the banks of the St. Lawrence River are accessible only by foot or boat. Within this rustic paradise, fishing is excellent--particularly for muskie in autumn. 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 9-hole golf course on the Island. One of the main attractions of the park is the Minna Anthony Common Nature Center, which includes educational exhibits, varied habitats such as wooded wetlands, 10 miles of shoreline and open granite outcrops, and miles of trails for hiking, cross-country skiing, snowshoeing, and nature education. The Nature Center provides educational and recreational programs for all ages.
