for anyone looking for a great Mountain Bike experience in the Northern Catskills , try the Elm Ridge trails just South of Windham off of Rte 23. We rode them this week and they were awesome. They were built a few years ago, by Mountain Bikers for Mountain Bikers, with State aid. Miles and miles of single track, banked and bridged, and switch backed. It really is a find, as there aren't too many places to Mountain Bike in that area except the lift served at Windham Mountain. You can get a map at the local bike shop, but the trails are very well marked with maps at major intersections
