Beacon Hill

Beacon Hill is a basalt outcrop in Connecticut that rises above the surrounding salt marshes with steep edges. The solidified lava formations create a distinct elevation in the otherwise flat coastal landscape.

The formation dates to the Triassic Period when lava flows hardened as North America separated from Africa and solidified into rock layers. These geological events shaped the basalt rock visible in the landscape today.

The trails connecting Beacon Hill integrate with the 28-mile Branford Trail system, offering numerous outdoor recreation opportunities for local residents.

The hill is accessible through a parking area at the end of Dominican Road, located just south of U.S. Route 1. Visitors should note this location in relation to the nearby highway when planning their visit.

A former stone quarry called Johnson's Quarry sits at the eastern base of the hill, marking industrial use at this site until 1942. This extraction activity shows how people took advantage of the natural basalt resources.
