Lake Dennison Recreation Area

Lake Dennison Recreation Area is a state park in Winchendon featuring a lake with a sandy swimming beach, forest trails, and organized camping zones. The site includes shower facilities, picnic tables, and a boat launch for visitors who bring kayaks or canoes.

The area began as part of a flood control project developed by the U.S. Army Corps of Engineers. Over time it evolved into a public recreation facility that serves the community and surrounding region.

The area draws visitors from across the region who come for swimming, camping, and fishing throughout the seasons. Local families and outdoor enthusiasts use the trails and shoreline as a gathering place for recreation.

The park is best visited during warmer months when all facilities and activities are fully open. Visitors should arrive early on weekends and holidays as popular areas fill quickly, especially near the swimming beach and picnic zones.

The area hosts the annual Massachusetts Triathlon, where athletes swim in the lake and bike and run across the surrounding terrain. This sporting event draws competitors from throughout the region and transforms the location into a focused athletic venue.
