There are two primary access points, and from these the trails are measured in hundreds, not thousands, of feet. But off-trail exploration will lead you to scenic vistas that are definitely worth the walk.
From East Haven center follow Main Street (Route 100) east and turn south on Hemingway Avenue/Route 142. Follow Route 142 for 1.6 miles to parking area on the right (south) side of Route 142 (now Short Beach Road) between Fairview Avenue and Stone Pillar Road.
