Hidden Valley, Moab Kamloops Trails Posted on Friday, April 21, 2017 by KamloopsTrailsFriday, April 21, 2017 We arrived late into Moab and decided to hike the Hidden Valley Trail, a 5 mile hike into the hills. The highlights were the numerous petroglyphs along cliff walls in a remote location. This was Day 1 of hiking in Utah for this trip. Related
