Close to Oaxaca, Mexico is a landscape that looks like it could be another planet – and there’s a turquoise natural swimming pool featuring one of the best views in the world. This otherworldly location is Hierve el Agua.
Hierve el Agua is one of the strangest natural phenomena you’re likely to encounter on your travels. There are two parts to the site. There’s a pool of mineral water at the top of a cliff, overlooking a waterfall, though no water actually flows over the cliff side.
