Thomaston Dam
Friday, February 14, 2025
| Other Names | Naugatuck River Valley |
| Last Known Status | Closed For Season |
This scenic area offers a great single track loop (for motorcycles only) with about 12 miles of trail covering 800 acres of public land. There are some technical sections with ruts and some short rocky climbs with tight cutbacks, but overall nothing too bad.
The area is generally open for trail riding during the summer months and weekends are often busy. There have been a couple years (2011-2012) that had delayed openings and early closures due to storm damage and downed trees, leaving a very short riding season.
During the winter, the trails are reserved for snowmobiling and cross-country skiing. Although some parts of the trail are fairly wide, ATVs and quads are not permitted. There is no camping on site but the day use area has picnic tables, restrooms, and water. The nearby model aircraft flying field also has tables and BBQ grills.
This area may close on short notice during and after inclement weather, so call first before heading out.
