Burnsville offers several distinct natural destinations: In the northeast, the Black Dog Unit of the Minnesota Valley National Wildlife Refuge covers 1,300 acres; in the southwest lies part of Murphy-Hanrehan Park Reserve. There are also trails along the Minnesota River, around lakes and a pond, and routes through forest, prairie and wetlands. For planning, it’s helpful to consider the destinations by landscape and trail length: the Kraemer Nature Trail is 0.5 miles long, Alimagnet Park has 2.9 miles of more difficult loop trails, and the Black Dog Trail is a 3.75-mile segment.

Protected Areas and River Landscape

The two protected areas differ in location and scope. The Black Dog Unit is part of the Minnesota Valley National Wildlife Refuge and lies in northeast Burnsville. It covers 1,300 acres. The 2,400-acre Murphy-Hanrehan Park Reserve spans Dakota and Scott counties, while only part of the protected area lies in southwest Burnsville. The 2,400 acres refer to the reserve as a whole, not just the part located in Burnsville.

The Black Dog Trail is a 3.75-mile segment of the Minnesota River Greenway. It runs along the Minnesota River through the Minnesota Valley National Wildlife Refuge. This makes it different from the individual loop trails around lakes and a pond: here, the focus is on the river and the protected area.

Loop Trails by Landscape and Length

At 0.5 miles, the Kraemer Nature Trail is the shortest of the loop trails mentioned. It passes through prairie and wetlands and includes a self-guided interpretive tour. A 0.9-mile loop at Lac Lavon passes through wooded areas and along two lakes. At Earley Lake, a 1.1-mile loop follows a boardwalk. The trails thus differ not only in length, but also in whether prairie, wetlands, forest or lakes shape their routes.

The loop at Sunset Pond is 1.65 miles long and runs around a pond and through a prairie restoration area. Alimagnet Park, by contrast, has 2.9 miles of more difficult loop trails through mature forests. The comparison highlights two different focuses: at Sunset Pond, the pond and restoration area shape the route, while at Alimagnet, the difficulty level is also explicitly stated.

A Beach Alongside the Trail Destinations

Crystal Beach offers something different from the loop trails: The park covers 24 acres and has an unsupervised swimming beach. In 2026, temporary access restrictions due to construction should be expected at Crystal Beach; check the latest access information before visiting.

For planning your trip, the nature destinations can be distinguished by trail type and landscape. The loop trails pass through their respective named environments; the Black Dog Trail, by contrast, is a longer segment along the river through the refuge. A difficulty level is also specified for Alimagnet. These differences offer practical points of reference for deciding what to focus on during your stay in Burnsville, without assuming that the individual locations form one continuous route.
