You almost have to know about Warren to find it. It straddles some of the highest hills in Litchfield County and opens up into rolling farm lands among heavily wooded acreage. Above All State Park sits on the mountain know as Above All, which has an evaluation of 1,480 feet above sea level.

The Shepaug River marks its eastern boundary, flowing from the Upper Shepaug Reservoir at the northeastern corner of the town. Some of the town’s vast woodlands are part of Wyantenock State Forest, which spills out to the west into the hilly town of Kent.

Warren, formerly a part of Kent, was settled about 1737. The parish of East Greenwich was organized in 1750. In 1786, a town was incorporated and named for a Massachusetts man, Gen. Joseph Warren, the Revolutionary hero, who lost his life at Bunker Hill. The town consists of a high plateau, bordered on the south by Lake Waramaug. Although natural in origin, the surface elevation of Lake Waramaug has been raised by a small concrete and masonry dam. The surface area is of the lake is approximately 680 acres. The lake has a maximum depth of 40 feet, an average depth of 22 feet, and contains approximately 4.8 billion gallons of water. The fish species observed in Lake Waramaug include largemouth, smallmouth and calico bass; lake and rainbow trout; yellow and white perch; pickerel, alewives, sunfish, and bullheads.

The blue-marked Mattatuck Trail runs from Prospect Mountain along abandoned roads to Flat Rock, where connection is made with the Appalachian Trail coming east from Kent Falls along the northern boundary of the town. (Flat Rock may be reached at some seasons by car, on road to east just beyond Cornwall line.) The signboard reads: "New Haven, 62 miles; Mt. Katahdin, Maine, 619 miles; Mt. Oglethorpe, Georgia, 1439 miles."

The tiny village of Warren has an interesting Congregational Church, with fine interior woodwork. It was built in 1818, during the pastorate of Rev. Peter Starr, who served for 57 years. About 1 1/2 miles north of the village, and a road turns west to a brick school house built around 1793; it is one of the oldest in New England in continuous use.

Warren is one of three towns in the Region 6 school district. It educates its youth at the Warren Elementary School through grade 8 and then sends them to Wamogo Regional High School in Litchfield.
