Agua Azul is a breathtaking sight, with its powerful and dazzling white waterfalls thundering into turquoise (outside rainy season) pools surrounded by verdant jungle. On holidays and weekends the place is packed; at other times you’ll have few companions. The temptation to swim is great, but take extreme care, as people do drown here. The current is deceptively fast, the power of the falls obvious, and there are many submerged hazards like rocks and dead trees.
If you're in decent shape, keep walking upstream – the crowds thin out the further up you go.
The turnoff for Agua Azul is halfway between Ocosingo and Palenque, some 60km from each. A paved road leads 4.5km down to Agua Azul from Hwy 199. A well-made stone and concrete path with steps runs 700m up beside the falls from the parking area, which is packed with food and souvenir stalls. Basic lodging is also available.
Unfortunately, theft isn’t uncommon, so don’t bring valuables, keep an eye on your belongings and stick to the main paved trail.
