About Colchester

Colchester is a quiet, tight-knit town of around 1,100 people in western Illinois, offering relaxed rural living with easy access to neighboring hubs. Sitting right along Route 136, it is just a ten-minute drive northeast to Macomb, where residents head for shopping, dining, healthcare, and Western Illinois University. Wide-open farmland surrounds the community, making it an appealing option for anyone seeking affordable space and a slower pace.

One of the biggest perks of living here is having Argyle Lake State Park just a couple of miles north of town. The park spans roughly 1,700 acres of wooded hills, scenic hiking trails, fishing spots, and quiet campsites. Families also appreciate having local schools close by, with the West Prairie district operating both an elementary and middle school right within Colchester. It all adds up to a comfortable, outdoors-friendly community with classic Midwestern charm.
