Cascadas de Agua Azul in Chiapas, southern Mexico, is a river valley where bright turquoise water descends over tiers of pale limestone in a long sequence of waterfalls and pools. Set in the municipality of Tumbalá in northern Chiapas, the falls form the core of a protected flora and fauna area that preserves a stretch of river and forested slopes in the Grijalva–Usumacinta basin.
The blue river stepping through limestone terraces
The heart of Cascadas de Agua Azul is a stretch of the Xanil River that drops over a limestone ridge in a series of cascades and pools extending for several kilometres along the valley floor.a stretch of the Xanil River As the water flows over the pale rock it breaks into many separate curtains and channels, gathers again in basins, then spills onward along the riverbed in a repeating pattern.
The stepped profile at Agua Azul is shaped by natural limestone terraces built up by mineral-rich water that deposits travertine as it moves downstream.natural limestone terraces A long succession of rimstone dams creates shallow pools where the turquoise colour is especially visible, while low drops between them form countless small waterfalls. The overall effect is more of a staircase of water than a single high fall, with the river threading through dense vegetation on the surrounding slopes.
A protected flora and fauna area in northern Chiapas
Cascadas de Agua Azul lies in the northern part of Chiapas in Tumbalá municipality, close to the boundaries with Chilón and Salto de Agua.Tumbalá, Chilón and Salto de Agua The falls and the adjoining forest form the core of the Área de Protección de Flora y Fauna Cascada de Agua Azul, a conservation area recognised under Mexican law that covers several thousand hectares of tropical landscape.Área de Protección de Flora y Fauna Cascada de Agua Azul
The protected area grew out of an earlier special biosphere reserve created in the twentieth century and was reclassified as a flora and fauna protection area in 2000.reclassified as a flora and fauna protection area in 2000 Within its boundaries the river corridor, smaller streams and forested hillsides are managed together, giving the valley a mix of open viewpoints over the cascades and more enclosed stretches where the river winds through dense trees and undergrowth.
Turquoise water, forest backdrop and extended cascades
The name “Agua Azul” refers to the distinctive blue colour of the water, which comes from dissolved carbonate minerals carried from the limestone bedrock and suspended in the flow.the distinctive blue colour of the water These minerals interact with light to produce shades ranging from pale turquoise in calm pools to deeper blue in faster, aerated sections of the river.
The cascades themselves are formed by contributions from several rivers, including the Otulún, Shumuljá and Tulijá, which combine to create channels and canyons of varying depth along the valley.contributions from several rivers Over a total vertical drop of around 200 m (656 ft), the water descends across hundreds of individual steps, while surrounding forest provides a green backdrop that contrasts with the light-coloured rock and the bright water.a total vertical drop of around 200 m
