My husband and I went out with Murphy for a day of rock climbing and had an amazing time!! This is a must do experience while in Joshua tree even if you have little to no rock climbing experience. Murphy gauged our experience level and then took us out to two different spots, expertly set up multiple climbs of increasing difficulty, and gave us great tips on rock climbing and other places for rock scrambling and hikes to check out in the park. Though we had just met him that morning, it was more like learning from a trusted friend and didn't have the feel of a touristy, paid experience. He was incredibly kind and patient, very safety conscious, and we had an absolutely wonderful time!
