What it is like in Union
Union is a town in Tolland County with a population of 805 and a land area of 28.85 square miles. It borders Ashford, Woodstock, Stafford, Eastford and Willington.
Union was the last town settled east of the Connecticut River, largely because of its rough terrain and poor soil. Graphite was found there early on, and in 1720 the General Assembly sold the land to 12 proprietors. Town offices are at 1043 Buckley Highway.
The town has a free public library, a Historical Society that keeps a museum in the old town hall on the Town Green, and a pavilion where the annual Old Home Day is held.
Bigelow Hollow State Park at 298 Bigelow Hollow Road is open daily from 8 a.m. to sunset. Mashapaug Lake covers 287 acres and has a launch for trailered boats with a 10 mph limit, while Bigelow Pond is about 25 acres and does not allow motors. Hiking, fishing and warm-season scuba diving in a small cove are allowed, and the park is used for cross-country skiing and ice fishing in winter. Camping is not permitted.
Together, Bigelow Hollow and Nipmuck State Forest cover more than 9,000 acres. The Mountain Laurel Sanctuary is another listed outdoor stop. Old Home Day is held each year at the Pavilion in the Grove.
