Iona Island

A 556-acre bedrock island nestled in the Bear Mountain State Park, Iona Island is bordered by meadows, marshes, shallows, and mudflats offers incredible paddling and wildlife viewing opportunities. Iona Island is part of the New York State Birding Trail, which highlights world-class birding opportunities across the state.

A variety of waterfowl, wetland birds, deer, muskrats, turtles, frogs, fish, and crabs call the marshes of Iona Island their home, and bald eagles often roost on the island in the winter. Iona offers important opportunities for research and education as well as being a National Natural Landmark designated by the National Park Service.

Enjoy Iona Island through the free public canoe programs offered by the Reserve every summer, or from the peaceful overlook off of Route 9W. Note that there is no public canoeing or kayaking allowed in the marshes surrounding Iona Island.

Iona Island is one of four sites in the Hudson River National Estuarine Research Reserve.
