Start with about 50 yards on limestone trail before ducking into the woods along the creekside Connector trails. For the next 1.5 miles you'll twist and wind along the Koshkonong Creek. You never knew 7' of elevation change could be so much fun. Lots of quick twisty sections, and a couple of fun obstacles if you keep your eyes open. Some beautiful scenery and wildlife. Listen for the slap of beaver tails! Twice the trail dumps back onto the limestone.
Just cross the bridge over the creek and join right back up on the singletrack. It is well marked. On the maps the northern most section of trail is White River. The middle section is Beaver Hole. And the southernmost section is Fat Tracks.
