Cedar Island

Cedar Island State Park is a small island park located in the St. Lawrence River near Clayton, accessible only by boat, offering primitive camping and natural island experiences. The park features wooded terrain, rocky shorelines, and scenic views of the Thousand Islands region. Visitors can enjoy fishing, swimming, and exploring the island's trails while experiencing the relative solitude of island camping. The park is part of the extensive network of island parks in the Thousand Islands region.

The park's location along the St. Lawrence River or Lake Ontario creates diverse aquatic and terrestrial habitats supporting abundant wildlife. Waterfowl including Canada geese, mallards, wood ducks, and great blue herons frequent the shorelines and wetlands throughout the year. White-tailed deer, red foxes, raccoons, and eastern cottontails inhabit the wooded areas, while beavers and muskrats are common in wetland habitats. The waters support excellent fisheries with species including bass, northern pike, walleye, and panfish, while bald eagles and ospreys hunt fish from above during warmer months.

Forested areas feature mixed hardwood communities typical of upstate New York, with sugar maple, American beech, red oak, and white ash forming the canopy. Understory vegetation includes flowering dogwood, witch hazel, and various shrubs providing food and cover for wildlife. Spring wildflowers including trillium, jack-in-the-pulpit, wild ginger, and bloodroot create colorful displays before the canopy fully develops. Wetland areas support different plant communities with red maple, ash, cattails, sedges, and various aquatic plants. The diverse plant communities provide year-round visual interest and support complex food webs.

The park's terrain was fundamentally shaped by continental glaciation during the Pleistocene ice age, with glaciers retreating from the region approximately 12,000 years ago. Glacial deposits including till, outwash, and erratic boulders are scattered throughout the landscape. The underlying bedrock consists of sedimentary rocks including shale, limestone, and sandstone deposited in ancient seas 350-400 million years ago during the Devonian and Silurian periods. Post-glacial processes including stream erosion, weathering, and soil formation continue to modify the landscape. The relatively flat to gently rolling terrain typical of much of the park reflects both bedrock structure and glacial smoothing.

The park experiences a humid continental climate typical of upstate New York, with four distinct seasons throughout the year. Winters are cold with average temperatures ranging from 15-30°F, bringing significant snowfall that enables winter recreation activities. Summer temperatures average 65-80°F, providing pleasant conditions for hiking, camping, and water activities. Spring and fall offer mild temperatures with spectacular seasonal changes, including vibrant fall foliage displays typical of the region. Annual precipitation averages 35-40 inches distributed fairly evenly throughout the year, with lake effect snow increasing totals in areas near the Great Lakes or Finger Lakes.

The Thousand Islands region has been inhabited for thousands of years, with the Haudenosaunee (Iroquois) and other indigenous peoples utilizing the rivers and islands for fishing, transportation, and seasonal settlements. The St. Lawrence River served as a crucial water highway connecting the Great Lakes to the Atlantic Ocean, with French explorers arriving in the 1600s. The area saw military action during the French and Indian War and the War of 1812, with fortifications built along the strategic waterway. The 1800s brought commercial shipping, logging, and the development of tourism as wealthy families built elaborate summer estates on the islands.

The park was established as part of New York State's expanding park system during the mid-20th century as recreational demands increased with population growth and automobile ownership. Land acquisition occurred over several years through purchases and donations from private landowners, with some parcels having previously been farmland or timberland. Development of facilities including campgrounds, trails, beaches, and picnic areas took place in phases, with Civilian Conservation Corps possibly contributing to early infrastructure in some cases. The park has been expanded and improved over the decades with additional land acquisitions and facility upgrades. Today Cedar Island is managed by the New York State Office of Parks, Recreation and Historic Preservation as part of the statewide park system serving millions of visitors annually.

Primary recreational activities include hiking on maintained trail systems offering varying difficulty levels and distances. Swimming and beach activities are popular during summer months at designated swimming areas with lifeguard supervision. Boating and fishing access allows visitors to enjoy water-based recreation, with boat launches serving both motorized and non-motorized watercraft. Picnic areas with tables, grills, and shelters provide day-use facilities for families and groups. Winter activities may include cross-country skiing, snowshoeing, and ice fishing when conditions permit. Nature observation and wildlife photography attract visitors year-round, with seasonal changes offering different viewing opportunities.

The park offers camping facilities with tent sites and RV-accessible sites equipped with electric hookups, though specific amenity levels vary by site. Restroom and shower facilities serve the camping areas during the operating season. Day-use areas include parking lots, picnic grounds with tables and grills, and playgrounds for children. Beach facilities include changing areas and seasonal concession stands during peak summer months. A park office provides visitor information and assistance during operating hours. The park is typically accessible from May through October, though some facilities may operate on extended schedules. Entrance fees apply during peak season, with camping requiring advance reservations. The park is located within driving distance of nearby communities offering additional services.

The park is managed by New York State Office of Parks, Recreation and Historic Preservation with focus on balancing public recreation with natural resource protection. Conservation efforts address invasive species management including emerald ash borer, hemlock woolly adelgid, and non-native plants that threaten native ecosystems. The park implements sustainable practices including erosion control on trails, water quality monitoring, and habitat restoration projects. Educational programs help visitors understand local ecosystems and their role in conservation, while ongoing monitoring tracks wildlife populations and ecosystem health to inform adaptive management strategies.
