Numerous parks, trails, lakes, and rivers nearby offer plenty of outdoor activities such as hiking, biking, camping, and fishing.

History of Spring Grove, the Rainiest Place in Minnesota

Spring Grove, Minnesota, is located in Houston County and was founded in 1855, when the first post office was officially operating. The first families to settle in the area were two brothers from Norway who had been living in Wisconsin for several years. They purchased land that had originally been part of a larger tract owned by the United States government and began farming it. About 20 more families followed soon after, with most coming from Germany, Sweden, and Norway and settling within a few miles of each other.

By 1870, Spring Grove had grown to include over 800 people as well as a variety of businesses such as general stores, blacksmiths, hotels, and saloons. In 1895 the population peaked at 1,124 residents before declining due to out-migration caused by better job prospects elsewhere or changes in agricultural practices, which made farming less profitable. Today there are just over 1,250 people living in Spring Grove. Thetown retains many aspects of its original identity, such as its strong Norwegian heritage celebrated through annual events like the Syttende Mai Parade & Festival on May 17th each year.
