This highlight marks the beginning of the trail that runs through the St. Croix Savanna Scientific and Natural Area. You have to drive through several blocks of recent development to reach the trailhead, but once you are on the trail, you feel like you are experiencing the pre-settlement prairie. The Big Bluestem prairie grass will tower above your head as you walk the trail, although you can still see the magnificent groves of Bur Oak towering above the grass.
