Connecticut’s Undeveloped Woodland Retreat — Larkin State Park Trail, Forested Hills, Horseback Riding, Mountain Biking & Free Parking Between Naugatuck and Middlebury
Whittemore Glen State Park is an undeveloped state park spanning portions of Naugatuck and Middlebury, Connecticut. The park features forested hillsides, the Larkin State Park Trail (a 10+ mile scenic rails-to-trails path), opportunities for hiking, horseback riding, and mountain biking, and free parking off Route 63.
Whittemore Glen is one of Connecticut’s quiet, undeveloped state parks — a forested retreat without the crowds, lifeguards, or restroom buildings found at the state’s larger parks. The park’s primary draw is its position along the Larkin State Park Trail, a scenic 10+ mile rails-to-trails corridor that passes through Middlebury, Naugatuck, Oxford, and Southbury along a former railroad grade. The flat, wide trail surface makes it accessible to hikers, bikers, and horseback riders alike. Beyond the Larkin Trail, the park’s forested hillsides offer additional exploration for those seeking solitude. With no entrance fee, no parking fee, and no development, Whittemore Glen rewards visitors who come prepared for a self-sufficient outdoor experience.
