Glenwood Hot Springs, Colorado - Guests at this Colorado Rockies lodge relax in the world’s largest hot springs pool, where 3.5 million gallons of nearby Yampah Springs water flow into one of two bubbling mineral pools daily. The temperature in the smaller therapy pool is a steamy 104 F. The larger pool, which measures more than two city blocks, is kept at a balmy 93 F.
The "Wave" near the Utah-Arizona border. Only 20 permits to hike this are issued daily and you have to apply for a lottery-like draw four months in advance for a chance to hike here. Definitely a bucket list place!
