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.

Trail is clear and running great. Hit it early (9am) and only saw one person when I was finishing the loop. Clear of trees and great dirt, with the exception of a little dry in the clear-cut areas.

Rode April 30th top to bottom. The upper section from trail start through the first set of switchbacks is open-ish. Once you get below the switchbacks, you’ll need to follow the directions below, bail out onto C-4010 and pick the trail back up after it crosses the road. After that, everything is running great. Some muddy/tacky patches if you’re in the deep woods. Everything with even a touch of sun exposure is nice and dry.

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.
