7. Golden Nugget Shark Tank, Las Vegas
Vegas has a lot of awesome pools that are more party palaces than swimming holes, but this one oozes cool for another reason. With a name like Shark Tank, it’s no great surprise to hear that you’ll be swimming with sharks here. Don’t worry, they’re behind protective glass of the aquarium along with other colorful aquatic animals, but you’ll feel like you’re immersed among them. It that’s not enough for you, there’s a three-story glass tubed waterslide (the Shark Chute) slicing through the aquarium just to give you an added adrenaline rush.

8. Hanging Gardens Resort, Bali
If this five-star Balinese boutique hotel pool doesn’t make you say ahhh, nothing will. The stunning split-level swimming sanctuary is suspended over the lush jungle with undulating curves. It’s lined with Batu Candi stone with geometric walls of solid volcanic ash, giving it a distinctive natural ambiance. The top level cascades below to the bottom tier for a soothing waterfall effect. It’s little wonder this photogenic spot often tops lists of cool hotel pools.

9. The Library, Koh Samui
One one hand, this exotic Thai pool separates itself from the rest by going with a signature scarlett shade for its beachfront bathing oasis. However, there’s something about this red hue that makes one think shark attack or bloody massacre. It’s just the pretty mosaic tiles of red, orange and yellow jewel-toned squares that have this effect, but perhaps they should have run this by a few focus groups first. Chaweng Beach is inches away if you’d prefer a less jarring soak in the big blue sea.
