Marina Bay Sands, Singapore

The infinity pool at Marina Bay Sands is the largest of its kind in the entire world—giving tourists a chance to take in the city from every point of view. It's part of the over-the-top Sky Park, perched atop the 57th floor of the Marina Bay Sands resort in Singapore. Unfortunately, pool access is only reserved for hotel guests, but a stay here is worth lounging by this revolutionary pool. (Bonus fun fact! It was just featured in the hit movie Crazy Rich Asians.)

Sail great lengths at San Alfonso Del Mar, Chile

Unusual and unrivalled in its size, the pool at San Alfonso Del Mar is the largest outdoor swimming pool in the world. It’s around 1,000 metres long (20 times the size of an Olympic pool) and around 35 metres deep, which also makes it the world’s deepest swimming pool to boot. Built along the Chilean coastline, the pool pulls in water from the sea, which is controlled and filtered via its own system. Navigate from one side to the other in one of the pool’s small sailboats and canoes, before anchoring up at the other end and heading down to the beach for an early evening stroll.
