Introduction: What? : This strenuous challenging 5.3-mile out-and-back trail leads through a desert canyon to a natural hot spring and the Colorado Riverbank. There are several amazing hikes near Las Vegas, NV but in my opinion, this is probably the most rewording one-of-a-kind hiking experience in the area. The he second hike on my list is hiking to Arizona Hot Spring just on the Arizona side of the Colorado River.
