Big Deer State Park offers 22 tent/RV sites and 5 lean-to shelters within the 26,000-acre Groton State Forest, making it an excellent base camp for accessing multiple recreational activities including fishing, boating, hiking, and mountain biking.

The campground features restrooms with flush toilets, hot showers, and available firewood, with check-in at nearby Stillwater State Park.

Campers can enjoy free day-use access to six other parks in the forest, including Boulder Beach for swimming and multiple lakes for boating and fishing.
