Agua Azul, Chiapas
This is arguably one of the best known and most-visited of all Mexico’s waterfalls, so it makes sense to kick off our guide with Agua Azul, Chiapas. Literally meaning ‘Blue Water’, if you’ve visited before you’ll know exactly why it’s named as such – the water is almost dazzlingly aquamarine due to the mineral content and flows down over several falls and pools, many of which you can swim in. However, avoid the rainy season (June to September) because that’s when the waters turn a muddy brown colour.
