Groton is a city in northeastern South Dakota. First organized in 1881 as a railroad stop, the Burlington Northern Santa Fe Railroad continues to provide major freight service through the southern side of the city. The city also is now located at the junction of two major highways (US Highway 12 and SD Highway 37). Sometimes listed as a bedroom community to the larger city of Aberdeen (just 18 west of Groton), Groton has a small, but healthy business district along Highway 12 and downtown, and offers a large range of recreation activities for a wholesome, active, outdoor lifestyle.
