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.
