There are a bunch of trails along I-70 heading west from Denver. Bill Moore comes to mind, but it is early season so you will encounter snow. If you are thinking Kokapelli, never done it, I understand there is a deep water crossing this time of year, maybe Chris Davis will chime in on that one. If you are heading that far west, Moab is a couple hours further.....this time of year that is my recommendation!
Hope it helps!!!
