Little Spruce Mountain is a 2,505-foot peak located in the Groton State Forest southwest of Beaver Brook. It offers views of the surrounding hills and valleys.

The acquisition of Groton State Forest began in 1919. The Forest is managed for timber resources, wildlife habitat, and recreational activities. Many rare, threatened, and endangered plants and animals occur in the Forest. The most sensitive species are associated with the cliffs, bogs and swamps, lakes, and forests around lakes.

Groton State Forest is home to seven state parks, the Groton Nature Center, and eight lakes and ponds. The area was once home to 12 sawmills and remnants are still visible. The Civilian Conservation Corps (CCC) was instrumental in developing the area, constructing roads, trails, fire lookouts, and picnic shelters, and planting trees within the forest. Glaciers covered the area 10,000 years ago and their retreat created the mountainous terrain mixed with streams, ponds, bogs, and wetlands.

Groton State Forest is also home to several state-designated natural areas, such as Peacham Bog Natural Area (748 acres) and Lords Hill Natural Area (25 acres).

Groton State Forest is open for varied and dispersed recreation, including but not limited to camping, hiking, swimming, boating, fishing, hunting, trapping, horseback riding, cross country skiing, and snowshoeing. The Montpelier and Wells River Railroad bed was converted to a multi-use trail and is part of the Cross Vermont Trail. Snowmobiling is allowed on designated VAST trails.

The trail to the summit is about 4 miles round trip, with an elevation gain of about 350 feet. The trail starts at a parking area on Spruce Mountain Road and follows an old logging road for the first mile. Then it turns into a narrow and rocky path that climbs steadily to the top. There is no fire tower or lookout on Little Spruce Mountain, but there are some open areas where you can see the nearby peaks of Spruce Mountain, Hardwood Mountain, and Kettle Mountain.
