The Cowling Arboretum is open to public use year round. The Cannon River is a popular fishing spot, and the upland and lowland forests along with the 150 acre prairie restoration provide excellent bird and wildlife watching opportunities. Among the species of note is the endangered tall-grass prairie specialist Henslow Sparrow (Ammodramus henslowii). Cowling Arboretum boasts an extensive 15-mile trail system that has been ranked by Runner’s Magazine as the top place to run in Minnesota, and one of the top 10 in the country. In the winter, trails are groomed for both classic and skate skiing. The Arboretum is a delightful place to walk any time of the year.
