other posters reminded me of trail names we rode (spent 4 days there), snodgrass, deadmans gulch also great. we didnt "feel" the thin air which surprised me, but the heat and totaly dryness mean we hammered water consumption like never before. We took to freezing a 1L bottle of water overnight and throwing it in the backpack, by the time we'd drained our 3L bladders it'd melted and we had another (nicely cool) litre to pour into the bladder.
403 trail, making most of mate/guide needing to check route book
scenic view from cottonwood pass on drive to CB
Monarch Crest with Munqe Chick in there somewhere
Really cool town with a great atmos, its too far from any airport to have been over-developed as a ski resort so its still got a small town, frontier feel but with everybody there for the outdoors and quality of life.
