Located on the southern border of Caledonia County, Groton is bounded by Peacham, Ryegate, Plainfield and Topsham. The surface of the town is diversified by hill and valley, presenting a picturesque landscape. Wells River, which rises in Groton Pond, flows through the town from northwest to southeast and historically afforded many opportunities for mills and machinery.

Groton is home to several beautiful ponds, including Groton, Levi, Ricker, Pigeon, Noyes and Kettle. Much of the town’s wilderness beauty is protected within Groton State Park, a 25,000-acre forest and the second largest protected area in the state. Within its boundaries are six state parks and year round recreation.

Despite being nestled between Interstates 89 and 91 and containing a number of roads and trails, the park maintains a wild atmosphere of the northeast once lost, and now returning. Today, State Highway 232 (also called the Groton Forest Highway) snakes its way north/south through the heart of the state forest. The state forest is serviced by a vast network of hiking and multi-purpose trails for mountain biking, horseback riding, and off road use. In the winter, the network of trails that surround the Groton Nature Center, located on the shore of Lake Groton, are used for snowshoeing and cross country skiing.

Groton was chartered in 1789 and organized at the first town meeting in 1797. The first settlement in Groton came in 1787. President Abraham Lincoln once pardoned Groton native Private William Scott, a member of the 3rd Vermont Infantry. Scott, commonly known as “The Sleeping Sentinel,” had been sentenced to death after falling asleep at his post. Scott would die in a later battle due to several gunshot wounds. Groton is accessed by Route 302, off I-91, and Route 232 off Route 2. Groton Village is located in the southeastern part of town along Route 302.
