Leave the big city and its chaos behind and spend some time and recharge in Castle Valley. It’s only 20 miles away from Moab. You’ll find adventure and some of the most breathtaking scenery in the state. Castle Rock, or Castleton Tower as the locals call it, is the No. 1 attraction. The 400-ft sandstone tower which rests on a 1,000 feet cone of looser rock, rises high above Castle Valley.
