Algonquin State Forest is a Connecticut state forest located in the towns of Colebrook and Winchester. The forest is managed for wildlife habitat and passive recreational activities. It contains two areas of special ecological importance: Sandy Brook Natural Area Preserve and Kitchel Wilderness Natural Area Preserve, the later donated by Helen Binney Kitchel in 1961,[1] both protected as Forever Wild by state statute. The forest offers opportunities for hiking, wildlife viewing, and letterboxing.
