From the trailhead in Interstate State Park, cross the St. Croix River to join the Railroad Trail, which follows the river northeast. The trail gains the river bluffs via a long staircase—one of two climbs on this otherwise easy hike—and takes a wide path through hardwoods and pine to the town of Taylors Falls. Continue east and south to the pothole area, where the trail dips near the river before climbing back above it (mile 1.4). Here, glacial meltwater exposed basalt cliffs and drilled the potholes, some of which approach 70 feet in depth. For a closer look, take the .25-mile Pothole Trail. Return to the trailhead on the River Trail, between the road and river.
