The town is part of the Lower Connecticut River Valley Planning Region.

For such a small community, Middlefield has an abundance of wonderful history that goes back to the late 17th century and many first settlers of Connecticut.

The west side of Middlefield is flanked by the Metacomet Ridge, a mountainous trap rock ridgeline that stretches from Long Island Sound to nearly the Vermont border.

In the summer Peckham Park has little league baseball games going on almost every day of the week.

Residents can also enjoy picking fruit, playing golf, shopping, and eating at Lyman Orchards.

The state park's 285 acres (115 ha) offer trails, fishing, swimming, and picnicking.
