Centennial Watershed State Forest Access provides hiking permit access to 17-18 miles of scenic marked trails within the forest, with multiple trailheads including the Saugatuck Trail and Aspetuck Trail in the Fairfield County area.

A hiking permit (available at kiosks, the Aquarion Water Company office at 714 Black Rock Road in Easton, or by download) is required for all trail access.

The forest also offers fishing access to three reservoirs (Saugatuck, West Pequonnock, and Far Mill) with a separate fishing permit, though a current Connecticut fishing license is also required.
