Tajumulco Volcano
San Marcos
Tajumulco Volcano is a prominent stratovolcano located in the San Marcos department of western Guatemala. Standing at 4,203 meters (13,789 feet), it is the tallest mountain in Central America and part of the Sierra Madre de Chiapas range. The volcano features two summits, with the higher one containing a crater approximately 50 to 70 meters wide. Its composition consists mainly of andesitic-dacitic lava flows, including a notable lava flow descending from the north-western summit into a steep valley. Although its eruptive history is uncertain and no confirmed recent eruptions exist, historical reports from the 18th and early 19th centuries mention possible activity, which is now considered unlikely. The surrounding region is sparsely populated, with the nearest town, San Marcos, located about 14 kilometers to the southeast. Hiking Tajumulco is a popular but infrequent tourist activity, typically taking around five hours from the nearby hamlet of Tuichán. Climbers should be prepared for variable weather conditions, as the area is often shrouded in mist and clouds, especially from April to September.
