4. Sanctuary Swala Camp, Tanzania
Make like a hippo and lurk eyeball level in the waters of this limpid infinity pool in Tarangire National Park. From this stealth position, you can spy herds of elephants, leopards, impala, lions, giraffe, kudu and other wildlife hanging out by their own watering hole beneath the acacia trees. That’s one swanky safari sanctuary. Let’s hope the creatures don’t get the two water sources mixed up.

5. Joule Hotel, Dallas
This glass-front pool literally dangles over the edge in Dallas. The tenth floor cantilevered design juts eight feet beyond the walls of the hotel. It’s a small roof, so I guess they had to do something to make a little more swimming space. The view at the end of the lane is pretty stunning, if you’re brave enough to splash around in here.

6. InterContinental Festival City, Dubai
Taking things one step further, this crazy hotel pool not only juts out over the side of the rooftop, but it has a plexiglass bottom floor so you feel like you’re swimming on thin air. It may give you the sense that you’re about to plummet while you plunge, but it must be a bit of a thrill, don’t you think?
