2. San Alfonso del Mar, Chile
This beach is located between the largest artificial pool and the largest ocean on the planet Earth. San Alfonso del Mar is an integral part of the eponymous luxury resort. Beach of San Alfonso on the one hand is limited by the Pacific Ocean, and on the other – a swimming pool.
It would seem – why build such a vast pool right on the ocean? But pure water roomy basin with a constant temperature of 26 ° C, can completely replace the ocean, where the water can be cooled and 17 ° C. In addition, sea water, with its dangerous waves and currents, marine predators and other surprises is clearly losing the pool.
