East Rock, located in New Haven and Hamden, Connecticut, is 1.4 miles (2.3 km) long by 0.5 miles (800 m) wide at its widest point, although steepness of the terrain make the actual land area much larger.
Beside the high point, East Rock has three other distinct peaks: Whitney Peak, 300 feet (91 m), a sharp-sided pinnacle on the north side of the ridge; Indian Head, 310 feet (94 m), just south of the high point; and Snake Rock, 205 feet (62 m), the southern buttress of the ridge.

Whitney Peak and Lake Whitney (located at the western base of the mountain behind the dammed Mill River) are named after Eli Whitney, the inventor of the cotton gin and a former New Haven resident.
The Eli Whitney Museum, a museum and workshop with hands-on projects and exhibits on Eli Whitney and A. C. Gilbert, is located at the base of the dam.

On the summit of East Rock, clearly visible for miles below, is the 112-foot (34 m) Soldiers and Sailors Monument.
 The monument honors the residents of New Haven who gave their lives in the American Revolutionary War, the War of 1812, the Mexican War, and the Civil War.

East Rock is located entirely within the 425-acre (172 ha) East Rock Park, managed by the city of New Haven, which maintains a seasonal automobile road that climbs to the summit of the ridge, a network of trails, an environmental center, and a rose garden.
A number of recreation facilities are located at the southwest base of the ridge; these are also managed by the city.
The ridge is completely surrounded by the urban neighborhoods of New Haven and its metropolitan extension into south Hamden.
East Rock lends its name to the nearby upscale East Rock neighborhood of New Haven, known for its Queen Anne and Victorian architecture.
U.S. Route 5 borders the east side of East Rock while Interstate 91 crosses below Snake Rock to the south.

The Metacomet Ridge extends west from East Rock as series of smaller, unnoteworthy traprock outcrops to West Rock Ridge; it extends east over another series of traprock outcrops to Saltonstall Mountain and Peter's Rock.
The west side of East Rock drains into the Mill River thence to New Haven Harbor and Long Island Sound; the east side into the Quinnipiac River, thence to New Haven Harbor and Long Island Sound.
Both rivers abut the base of the mountain.
