Road bike routes
I strongly recommend the E bank of the Ashokan reservoir. There is an approximately three mile section with spectacular views that is closed to traffic (except for the middle portion). One can then continue on Rt. 28A, with still more views, or explore Beaverkill Rd. or numerous other local roads. If you follow 28 A, you can connect with Rt. 28 at various points and ride (with care, please -- this road has taken a disproportionate number of lives, though usually those of motorists) back to the campground. Though the res. section is flat, there are some stiff hills -- riding up Beaverkill Rd. will probably make you pant. At least, it does me. A fairly tough ascent is to take 28A from Boiceville, take the rt. turn after the bridge over the Beaverkill, and ride up through the Peekamoose notch all the way into Sundown, past the Ashokan High Point and Peekamoose trailheads--very picturesque indeed. For a truly evil hill ride, drive into Woodstock and ride up Meads Mountain Road -- I've never done this, have no intention of doing this, but see people considerably fitter than me doing it fairly regularly, albeit slowly and usually grimacing as they go. I ride a touring bike (RB-T).
