Bluff Point

Location: Groton, CT

Anchor Site(s): 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. One of the largest undeveloped coastal areas in the state, this mostly forested 800-acre site contains a variety of habitats supporting state-threatened and-endangered species.

Ecological Importance

  • The property includes a variety of coastal habitats including coastal forest, barrier beach and dune, grassland, coastal plain pond, coastal bluff, tidal wetlands, intertidal mud flats, eelgrass beds, and back-barrier sandflat.
  • More than 200 bird species are found here, including various herons, hawks, cormorants, and federally-endangered 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 type 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 nearly 100-years old.



Recreational Opportunities

• Take a two-mile round trip hike, from the parking area to the bluff along the dirt, for one of the finest views of eastern Long Island and Fishers Island Sound.

  • Walk another two miles, if you feel energetic, from the bluff along the barrier beach 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 shellfishing (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.

  • Routes leading to parking areas are posted with brown and white Long Island Sound Access signs.
  • Be sure to stay on trails and not disturb the site’s fragile habitats.

Did You Know?

  • Bluffs are steep coastal slopes created through long-term erosion—and one of LISS Habitat Restoration Initiative’s 12 priority habitats.
  • The trees on the eastern slopes, where soil is thicker, are 70-90 years old.
  • To maintain the grasslands, they are periodically mowed to prevent it from reverting to forest.
  • When water freezes it expands, generating up to 28,000 pounds of pressure per square inch. During the Great Freeze of 1780 water got into a crack in the boulder now known as Split Rock. When the water froze the boulder split apart with the sound of a cannon shot.
