This area is actually closed in the summer due to extreme temperatures, so there's no time like the present to check it out. It’s a six-mile gravel travel that leads past the imposing Liberty Bell Arch, past a WWII-era mine (and the remnants of an old mining cable car), and down to the tip of Black Canyon wihch overlooks the 1,000ft-deep Colorado River gorge. This trail is good for hikers of all abilities.
Accessible through the Lake Mead National Recreation Area, the Arizona Hot Spring is located in a dramatic volcanic slot named White Rock Canyon, which takes its name from the huge white boulders that were carried down into the canyon from flash floods. Fractures in the volcanic rock form pools of water upwards of 120 degrees just 1,000 feet from the Colorado River. The trail descends into the canyon, which means the 586 feet of elevation gain is all on the way back, and there is a 20-foot steel ladder to climb at one point. Aside from that, it's a relatively easy 5.6-mile round-trip hike. Just be warned: if you're planning on soaking in the springs, keep your head above the water – the National Park Service and CDC warn of killer amoeba lurking in the springs.
