Old Furnace State Park
Located in the Quiet Corner of Connecticut is a small state park known as Old Furnace State Park. Although the park is only 367 acres, this little known gem has many miles packed into the park. A ride can be upwards of 16 miles depending on how creative you get, but typically Old Furnace is the perfect place to sneak out for a 2 hour ride with a good amount of climbing.
Most of the trails are classic New England mountain biking; rocky, rooty and technical. The perfect example of this is a short steep rocky and rooty trail locals call Roots n Ladders, one climb up and you will understand where the name comes from. Another trail that that is the exact opposite; named Orange Crush, is approximately 3/4th of a mile of smooth climbing which leads up to a cliff lookout 200 feet above Upper Ross Pond, take the trail in reverse and it is a fast, smooth and flowy decent back towards the South Frontage Rd parking lot. There are also a couple fire road style trails that are perfect for beginners or just a mellow ride.
From the junction of Route 6 and Route 395 (Exit 91) in Killingly, proceed east on Route 6. Take the first right onto South Frontage Rd, Parking lot will be on the right (0.2 mile from Route 6).
