Crystal Lake lies between the towns of Tolland and Stafford on a five-mile-long triangular strip of land extending from the rtheastern corner of Ellington. Attracted by the lake s sandy shore surrounded by forests of oak, chestnut, pine, and maple, early families of settlers called the lake Square Pond. In the 1890s, Crystal Lake became a destination resort. Its popularity extended through the advent of the interurban trolley and Depression-era auto trippers who stayed in the lake s hotels, cottages, and roadside tourist cabins. In the 1930s, the Sandy Beach Ballroom attracted the big bands of Duke Ellington, Guy Lombardo, and Cab Calloway. The ballroom also served as a roller-skating rink where young people from Ellington, Stafford, Rockville, and surrounding towns spent their leisure hours. Today Crystal Lake remains a popular getaway for fishing, swimming, and boating.
