- The Crystal Lagoon at San Alfonso del Mar resort, Chile, is large enough for sailing and comes with its own fake beach
At the San Alfonso del Mar resort in Chile, a quick dip could well turn into a marathon.
Swimming a length in this, the world's largest outdoor pool, would mean stroke after stroke for more than three fifths of a mile - that's 20 Olympic-size swimming pools.
The enormous man-made lagoon is set halfway up the country's Pacific coast, in the city of Algarrobo, and is filled with 66 million gallons of crystal clear seawater.
