West Hartford is adjacent to Hartford, the State capital, and neighbors Bloomfield, Newington, Farmington, and Avon.

West Hartford is a large community and one of the main retail centers in Hartford County. West Hartford Center is a shopper's delight with over 140 shops and boutiques and many restaurants with outdoor seating. Part of the renovated downtown is Blue Back Square, which includes a cinema, upscale shops, restaurants and luxury condominiums. A portion of the expansive Westfarms Mall extends from Farmington into the town.

The west side of West Hartford is flanked by the Metacomet Ridge, a mountainous traprock ridge line that stretches from Long Island Sound to nearly the Vermont border. Notable features of the Metacomet Ridge include Talcott Mountain and a number of highland water reservoirs belonging to the Metropolitan District, which maintains watershed and recreation resources on the property. The 51-mile (82 km) Metacomet Trail traverses the ridge. West Hartford is approximately 100 miles (160 km) southwest of Boston, Massachusetts and 100 miles northeast of New York City. I-84 runs through West Hartford.
