Simsbury lies in the northern end of the Farmington Valley. The east side of Simsbury, going toward the Capital city of Hartford, is flanked by Talcott Mountain, part of the Metacomet Ridge. This mountainous trap rock ridgeline stretches from Long Island Sound to nearly the Vermont border. Notable features of the Metacomet Ridge in Simsbury include Heublein Tower, Talcott Mountain State Park, Penwood State Park, and the Tariffville Gorge of the Farmington River. The 51-mile (82 km) Metacomet Trail traverses the ridge. At the western foot of the mountain, near the Farmington River, grows the Pinchot Sycamore, the largest tree in Connecticut.
The population in Simsbury has grown from 5,000 in 1950 to today’s population of over 23,000. The town covers an area of approximately 34.5 square miles and is geographically located in Hartford County, approximately 14.5 miles west of the capital city Hartford. While Simsbury has experienced development in the past few decades, the Town government has been sensitive to maintaining the rural environment and historic charm that makes Simsbury the quintessential New England Community.
