The trail is simple. I've ran from taylor park to aspen to have lunch so many times I can do it with my eyes closed. sounds like your starting in aspen so I'll go from there. Take the groomed trail till it ends all the way back and the ungroomed trail starts on the right. Hold on because if you haven't been that way before that is the worst trail I've been on in my life. Take that trail all the way out. that one is pretty self explanitory. Once you get to the top, out of all the meadows find the 4X4 posts. If you follow these posts they will take you over the pass. These are your trail markers they are couple hundred years apart. Once you get to the Taylor pass sign drop down to the lake below you. Towards taylor park. Once down on the lake head slightly left and this will take you around and downward. You should be able to pick up some tracks from there. The trail will take you down to the road to the Taylor Park Trading Post.
