Bluff Point State Park and Coastal Reserve

About the Site

Bluff Point is a state-owned peninsula often considered the last significant undeveloped area on the Connecticut coastline. In 1975, the Connecticut Legislature designated a portion of Bluff Point as a “Coastal Reserve” in recognition of its ecological importance and to preserve its ecological integrity. This mostly forested 800-acre site contains a variety of habitats supporting state-threatened and endangered species. 

Juliana Barrett, a coastal habitat specialist with Connecticut Sea Grant, highlights Bluff Point State Park in Groton, CT. Bluff Point showcases many different habitats, all located within 800 acres.

Ecological Importance
  • The property includes a variety of coastal habitats including coastal forest, beach and dune, grassland, coastal plain pond, coastal bluff, tidal wetlands, intertidal mudflats, eelgrass beds, and back-beach sandflat.
  • More than 200 bird species are found here, including various herons, hawks, cormorants, and federally-threatened piping plover.
  • Removal of a wastewater treatment plant discharge to Mumford Cove on the east side of Bluff Point resulted in the spontaneous restoration of eelgrass, a species of submerged aquatic vegetation providing critical habitat for shellfish, finfish, and waterfowl.
  • The southeast section of Bluff Point is a designated Connecticut Natural Area Preserve. The designation is due in part to a unique coastal forest on a concave slope, known as a ‘cove forest,’ which supports trees that are about 100-years old.
  • Bluff Point State Park is one of the locations that has been nominated for Connecticut’s first National Estuarine Research Reserve (NERR). View a map of the proposed site here. 
Recreational Opportunities
  • Take a two-mile round-trip hike, from the parking area to the bluff along with the dirt, for one of the finest views of eastern Long Island and Fishers Island Sound.
  • Walk another two miles from the bluff along the beach spit to its terminus at Bushy Point.
  • Use the car-top launch at the parking area to paddle the Poquonnock River and other nearby embayments.
  • Bird-watch within a variety of habitats that support more than 200 species of birds.
  • Check listings at the Denison Pequoutsepos Nature Center website and other area nature centers for guided hikes.
  • Go shell fishing (if you have a permit from the Town of Groton), or bring your pole to fish from the shore.
  • Find the pedestrian bridge in the northeast corner of the park for access to Haley Farm State Park. The park contains coastal grasslands, an increasingly rare vegetation community along Connecticut’s coast.
