The South Shore River's Edge Trail runs along the Missouri River. The trail is rated as moderate and is perfect for hiking, trail running, and mountain biking. It's an out-and-back, so you can go as far as you like.
To start, park at the South Shore Trail Trailhead (click the Get Directions link above). At the trailhead, there are vault toilets if needed. The trail goes east following the bluffs on the south side of the Missouri River.
After a mile, there will be a fork in the trail. To the left, is the Chaos, Mayhem, and No Tap mountain bike trails that are rated difficult. Continue on the right to stay on the moderate South Shore River's Edge Trail.
The trail continues another 2-miles to the Ryan Dam overlook. At this point, you can head back to the trailhead, or do the optional Lost Fork Loop. Lost Fork Loop is 3-miles, rated difficult, and is typically used by mountain bikers.
