The water's turquoise coloration is caused by light refraction off limestone deposits and volcanic sediments on the riverbed.
The reserve is situated in a transition zone between the temperate and tropical ecosystems of the Mexican Trans-Volcanic Belt.
Local conservation efforts have successfully prevented industrial development within the immediate riparian zone.
The reserve acts as a microclimate buffer, maintaining significantly higher humidity levels than the surrounding Altotonga municipality.
Pancho Poza Ecological Reserve is a protected natural area in Altotonga, Veracruz, featuring a crystal-clear river fed by mountain springs. The reserve spans approximately 10 hectares of cloud forest ecosystem, characterized by its distinctively turquoise-hued pools formed by volcanic rock formations. Visitors traverse a network of natural trails along the riverbank that lead to multiple cascading waterfalls and swimming spots. The area is home to endemic species of bromeliads, orchids, and various ferns typical of high-altitude Veracruz forests. Water temperatures remain consistently cool throughout the year due to the spring-fed source. The site functions as a biological corridor and serves as a vital water source for the surrounding agricultural community.
