Established in 1968, the Audubon Center of the Woods (ACNW) is a private, non-profit 501(c)3 environmental learning center (ELC) and green retreat & conference center on Grindstone Lake near Sandstone, MN – 90 miles north of Minneapolis/St. Paul. We offer a great variety of outdoor and environmental education experiences for people of all ages – youth, families and adults – and are an ideal K12 school field trip and student travel destination. In addition to our on-site programs and camps, ACNW provides outreach programs throughout the region. All of our facilities are also available for rental – perfect for hosting your own retreat or conference at our beautiful 535-acre lakeside location. The 535-acre (2.17 km2) sanctuary includes over 7 miles (11 km) of hiking and cross-country ski trails through a variety of habitats, such as old-growth red and white pines, hardwood forests, restored wetlands and prairies.
