Estación de Altura Altzomoni is a high-altitude weather station at an elevation of 3.985m (13,074ft) above the sea level, located in the Izta-Popo Zoquiapan National Park, in the State of Mexico. It’s one of the highest mountain roads of the country.
The surface of the road is cinder and sand. The unpaved sections of the road can be impassable when wet. In any case, driving 4WD is required. The road is usually impassable from October to June (weather permitting). Great trail for experienced wheelers. Avoid driving in this area if unpaved mountain roads aren't your strong point. Stay away if you're scared of heights. Expect a trail pretty steep.
The road to the station starts at the Paso de Cortés, a high mountain pass at an elevation of 3.400m (11,150ft) above the sea level.
