To Sua Ocean Trench
This paradisical pool isn’t, as it sounds, an ocean trench deep under the sea, but a ‘blowhole’. Translated unglamorously as ‘big hole’ To Sua, on the island of Upolu in Samoa, must be up there in the most amazing places to go swimming anywhere. Take the ladder to descend into its depths or, if you’re feeling brave, dive off it.
