Encompassing approximately 1700 acres, the Tivoli Bays are large freshwater tidal marshes on the Hudson River surrounded by undeveloped land. The area includes the North Bay which is an extensive marsh cut by meandering tidal creeks and fringed by tidal swamps and; the South Bay, a large, shallow cove with mudflats exposed at low tide; several islands; and two tributary streams.

The site is designated by the Audubon Society as an Important Bird Area (IBA) and is also considered an important spawning and/or nursery ground for a variety of freshwater fish species.
