Iona Island is located in Bear Mountain State Park on the east side of Route 9W in the Town of Stony Point in Rockland County, six miles south of West Point. Iona Island is a bedrock island in the midst of the Hudson Highlands, bordered to the west and the southwest by Salisbury and Ring Meadows, two large tidal marshes, the mouth of Doodletown Bight, an expanse of shallows and mudflats. A separate island, Round Island, was attached to the south end of Iona Island with fill in the early 20th century. The marshes and shallows occupy one mile between Iona Island and the west shore. In addition to being part of the Hudson River National Estuarine Research Reserve, Iona Island and its associated tidal wetlands have been designated a National Natural Landmark by the National Park Service.
The area of Iona Island is comprised of brackish intertidal mudflats, brackish tidal marsh, freshwater tidal marsh and deciduous forested uplands. Doodletown Brook is the principal tributary to the site, draining approximately 2.9 square miles. The Iona Island component encompasses 556 acres. The marsh at Iona Island can be viewed along the causeway (off Route 9W), accessible by car or on foot.
Excellent views of Iona Island can be seen from a number of vantage points, notably the overlook across the river on Route 6/202, which has parking for at least 15 cars. Several overlooks within Bear Mountain State Park also offer splendid views of Iona Island and its marshes. Lands west of the railroad crossing are accessible and offer limited views of the marsh.
