I have posted about our recent trio to Grutas de Tolantongo, in the arid mountains of the State of Hidalgo, on my other blog: Surviving La Vida Buena.
Tons of water emerge from hidden caverns and mountainside springs, to make a desert canyon in the Estado de Hidalgo into a spectacular oasis.
We'd visited Tolantongo in 2007, and were eager to return to experience the Paraiso Escondido area, with its long vistas and cascading warm springs pozas, tiered upon the hillsides. There are now two Tolantongos: the classic section closer to the Río and La Gruta, and the upper Paraiso Escondido section, nearer to the entrance station and place of pozas.
