Phoenix is known to have a few sweet places to cool down. When the Pointe South Mountain became the Arizona Grand Resort, the hotel and its pool got a facelift. What was once a glorified watering hole has become a seven-acre fun park. If you're up for a rush, take Slide Canyon Tower and choose among three slides, with 51- and 31-foot drops from the tower's fourth level. If the fast and furious water slide thing isn't your scene, grab a (free!) inner tube and jump in the lazy river or head to the wave pool — if not to surf some waves, then to check out the beach bodies catching the rip curl. The downsides: The pool's open only to guests and only until 4 p.m., which just means you'll have to make it a weekend and relax in the 25-person hot tub after a hard day's work on the slide.
