4. Powder House

Size: 100 acres
Access: The main access point into this Core Conservation Area is behind the Bolton Town Hall at 663 Main Street. Parking in the rear parking lot is available. Trail access is also available at the corner of Golden Run Road and Sugar Road but there is no parking. Another access point is at the beginning of Quail Run Road but this access is unavailable in the spring due to flooding conditions.
Description: Behind the Town Hall the area is wooded hillside providing a good climb via either the marked trail or the wider Old Town House Road. The Powderhouse, built for storage of ammunition was constructed in 1812 and sits up above Town Hall. Ledge and boulder outcrops make the hike up to the Powderhouse interesting. A large vernal pool is located near the entrance of Quail Run and the wooden boardwalk is usually under water during the spring.
