About Nipmuck State Forest
Nipmuck State Forest in Union covers over 3,000 acres in Connecticut’s far northeast corner — the state’s most remote and rural area. Named for the Nipmuc people, the forest includes Bigelow Pond, Yale Forest research plots, and some of the most intact northern hardwood forest in the state. The elevation and latitude create a forest more similar to Vermont than typical Connecticut.
Things to Do
Hiking, fishing in Bigelow Pond, swimming, hunting (deer, turkey, bear), mountain biking, camping at Bigelow Hollow, and cross-country skiing. The remote location and extensive acreage offer genuine wilderness feeling.

Wildlife & Nature
Nipmuck State Forest — named for the Nipmuc people (“freshwater people”) — protects 9,000+ acres in Connecticut’s Quiet Corner, making it one of the largest forest blocks in the state. The Nipmuck Trail traverses 34 miles through the forest — Connecticut’s longest blue-blazed trail. The forest’s extensive, unfragmented habitat supports interior-forest species that have declined elsewhere — wood thrush, scarlet tanager, and worm-eating warbler all breed in the deep forest interior. Black bears are occasionally reported. The forest borders Bigelow Hollow State Park, creating a combined conservation area exceeding 10,000 acres. Mashapaug Pond within Bigelow Hollow is one of Connecticut’s cleanest water bodies.
