Crystal Lake is a scenic and close-knit city with approximately 40,000 residents. First known as Crystal Ville, the town was first settled in 1836 by Beman and Polly Crandall along with six of their children. The family traveled from New York to the village in a covered wagon and constructed a cabin for their home. Throughout the 1850s, a network of railroads was constructed to connect the area with the burgeoning city of Chicago. Today, Crystal Lake still retains its old-world charm of yesteryear. One of the main attractions to the city is its public park system. Residents can enjoy over 1,500 acres of open space in addition to the 230-acre Crystal Lake for swimming, boating, and fishing.
