Lost Valley Loop is a roughly 9 mile ride out of the Fall Creek TH. Debates rage about route, but most people ride counter-clockwise so as not to miss the awesome descent on the McKenny Trail back down to Fall Creek. Thanks to trail work and re-routing over the past few years, this is now a year-round loop.

Half of it was great, felt like summer riding. The other half was pretty muddy and some good size puddles to play in.

Large tree down across trail (8" diameter), blocking trail right before the intersection of Lost Valley when headed down the hill towards Fall Creek. Moist ground with a few muddy puddles. The worse puddles seemed to be on the first half to the intersection with Mima Trail/Lost Valley in the opening. That tree at 45° on the ground is about 1/3 of the way along the trail. It can be rode around but should be removed as could be a hazard if coming downhill and not looking far enough ahead or if it's dark.

If you're riding a hard tail be ready for a bumpy ride through the clear cud the clay has dried around horse shoes and makes for a very uncomfortable section
