Tajumulco’s summit is 4,220 meters above sea level and the highest point in Central America. This volcano has been dormant for years, and the area around Tajumulco was declared a protected area since 1965.
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 50–70 metres (160–230 ft) wide. A lava flow from the northwestern 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 is unknown. Reports from the 18th and early 19th century do contain some dubious accounts of eruptions.
The region around Tajumulco is relatively sparsely populated. The nearest town of note, San Marcos, is located 14 kilometres (8.7 mi) to the south-east.
Although it is infrequently visited, the volcano can be climbed in about five hours from the hamlet of Tuichán. The high altitude requires acclimatization before the summit can safely be reached. Views are variable as the area is frequently covered in mist and cloud, with conditions at their least favorable between April and September.
