Tajumulco

Tajumulco is a stratovolcano located in the department of San Marcos, Guatemala. It is the highest mountain in Guatemala and the entire Central American isthmus. Its elevation is 4,220 meters (13,845 feet) above sea level. The volcano is situated in the Sierra Madre de Chiapas range and is part of the Central American Volcanic Arc.

The volcano is considered dormant, with its last confirmed eruption occurring around 850 AD. Evidence suggests a significant Plinian eruption at that time. However, fumarolic activity and hot springs are present on its slopes, indicating ongoing geothermal activity. The summit of Tajumulco is characterized by a double crater.

The slopes of Tajumulco are covered in pine and oak forests at lower elevations, transitioning to páramo vegetation and then bare rock and ash at higher altitudes. The climate is alpine, with cold temperatures and strong winds year-round. Snowfall can occur at the summit during the cooler months.

The volcano is a popular destination for hikers and mountaineers. The ascent is challenging due to the altitude and terrain, but the summit offers panoramic views of the surrounding Guatemalan highlands and, on clear days, the Pacific Ocean. The nearest major town is San Marcos. The indigenous Mam people inhabit the region around Tajumulco, and the volcano holds cultural significance for them.
