Volcán Tajumulco is a large stratovolcano in the department of San Marcos in western Guatemala. It is the highest mountain in Central America at . It is part of the mountain range of the Sierra Madre de Chiapas, which begins in Mexico's southernmost state of Chiapas."Tajumulco Volcano."

Description Tajumulco is composed of andesitic-dacitic lavas on the top of a large escarpment of uncertain origin. It has two summits, one of which has a crater wide. A lava flow from the north-western summit descends into a steep valley on the same side of the volcano.
The volcano's eruptive history is unclear and the date of its last eruption unknown. Reports from the 18th and early 19th century claim to record eruptions but these are considered unlikely.
The region around Tajumulco is relatively sparsely populated. The nearest town is San Marcos, located to the south-east. Although it is infrequently visited by tourists, the volcano can be climbed in about five hours from the hamlet of Tuichán. Views are variable as the area is frequently covered in mist and cloud, with conditions at their least favorable between April and September.
Geomorphology, Ecosystem, and Ascent Routes Tajumulco represents the highest point in Central America and forms part of the volcanic arc of the Sierra Madre de Chiapas. The stratovolcano features two distinct peaks: the eastern primary summit reaching 4,203 meters with a 50-to-70-meter wide crater, and the western secondary peak known as Cerro Concepción (3,800 meters). The surrounding high-altitude ecosystem transitions from sub-alpine pine-oak forests to cold paramo-like grasslands near the summit ridges, supporting specialized flora adapted to severe nocturnal frosts. +Physical and Volcanological Profile of Volcán TajumulcoVolcanological FeatureElevation / Technical ParameterGeomorphological & Ecological AttributesPeak ElevationsPrimary Summit: 4,203 m; Secondary Summit (Cerro Concepción): 3,800 mMain crater features a 50–70 m diameter basin; secondary cone exhibits eroded lava domes.Lithology & VolcanismAndesitic and dacitic lava flowsStratovolcano constructed over Tertiary metamorphic escarpments with unconfirmed historical eruptions.Bioclimatic ConditionsAlpine cold climate (4,203 m summit)Frequent nocturnal frosts (-4 °C to -10 °C) during winter months; high cloud cover from April to September.Forest ZoningSub-alpine conifer forest to zacatonalPresence of Pinus hartwegii and Abies guatemalensis, transitioning to high-altitude alpine bunchgrasses.Tuichán RouteStart at ~3,000 m (Tuichán Pass)1,200 m vertical gradient; standard 5-to-7 hour ascent leading to the inter-peak saddle and crater rim.
