Mcghies bike shop outpost offers rentals, maps and guides (we rode with guide Bobby, who was wonderful). We rode primarily moderate trials which still had plenty of technical sections, but spared us from some of the more difficult climbs. We rode 2 days, one of which was in a light rain. We enjoyed both trips and learned many of the local riders prefer slightly wet conditions. There are beautiful sandstone mountain views, desert views and lots of wildlife. If you are a cyclist visiting LV this is a 'must do'!!! Jaxon Hammond (57) about 1 year ago N/A: 1 Completed 1 Reviews So far my favorite near Las Vegas ! Joe Pyter (327) about 2 years ago N/A: 7 Completed 7 Reviews This is a heat trail. Plenty of challenging areas, and multiple trails. Go with some who knows the trails. There is McGhies bike shop in Blue Diamond which is a great meeting place.
