Santa Ysabel truck trail can be ridden either direction. West to east starts with a stiff 1.5 mile climb. Followed by 3.5 miles of up and downhill. Return trip makes the initial climb into a fast and fun, but not technical, descent. This is jeep trail all the way; usually open to motor vehicles, so beware. But it is occasionally closed to motor vehicles due to trail conditions; mud mainly, but can have serious road wash-outs after rains--- serious enough to swallow large 4x4's or mtb'ers who fail to look far enough ahead. And by the way, this is mountain lion country---I don't like to ride it close to dusk or after dark (unless I am with a group with slower riders;).
