World's Coolest Pools

Why It’s Cool: Crocodile lovers can get personal with the massive reptiles at this educational pool in Australia. An acrylic two-person cage (a.k.a. “the cage of death”) is lowered from an overhead monorail into a saltwater pool, where swimmers come face-to-face with 18-foot-long crocs—some of the largest down under. A glass wall bisects a croc-free section of the pool for those who want to engage from a distance.
Interesting Fact: Faint of heart? The complex also has a viewing pool (adjacent to the main pool) with 100 baby crocodiles.
