The north section starts where the trail down from the Visitor Center meets it and the South River Trail
. It's mostly crushed limestone with a bit of pavement at the southern end, and no big elevation shifts. Easy to run out-and-back if you don't want to go for a longer run out to the Prairie Loop
Along the way, you'll pass a couple picnic areas and a swimming beach on the shore of the St. Croix River.
Bald Eagles are commonly seen in the tops of dead trees along the trail.
