If you're a die-hard city gal, imagine yourself floating in the world's largest rooftop Infinity Pool, gazing down on the glittering city-skyline from 57 levels above. At the Marina Bay Sands Hotel in Singapore resides the world's largest cantilevered platform. Known as the SkyPark, it stretches longer than the Eiffel tower laid down, with an impressive 12,400 square meters of space. People around the world were amazed upon seeing an elevated swimming pool with vanishing edges. But swimming to the edge won't be quite as risky as it looks. While the water in the infinity pool seems to end in a sheer drop, it actually spills into a catchment area where it is pumped back into the main pool. At three times the length of an Olympic pool and 650ft up, it is the largest outdoor pool in the world at that height. Just imagine taking in a sunset or sunrise from that edge.

What's it like to swim in a pool of blood? This eerie hotel resort might give you an idea. The Library on the famous Koh Samui Beach in Thailand features a vibrant, ruby-colored swimming pool. It has a striking visual similarity to a pool of blood, making the whole thing look like a scene out of the Old Testament. Although it may look off-putting, the red colour in the extraordinary swimming pool is reassuringly not due to the water itself, so there's no risk in turning red after taking a dip. The vibrant hue is caused by the combination of red, yellow, and orange tiles which line the pool, which certainly makes it stand out next to the azure surroundings.
