The Long Meadow Lake Unit is one of eight units that make up the Minnesota Valley National Wildlife Refuge. It is the most visited of the eight units. It lies on the north bank of the Minnesota River just south of the Minneapolis-St. Paul International Airport. Fort Snelling State Park lies just across the river. In the spring of 2013 USFWS began an oak savanna restoration project on 5 acres near the Bloomington Visitor Center.
There are more than 18 miles of hiking trails. Casual visitors can hike the 1 mile Hillside Trail or the 1.3 mile Bass Ponds Interpretive Trail. For a somewhat longer walk, there is the 7.3 mile north loop trail. Serious hikers can take the 16 mile south loop trail.
