Pacaya: A Deep Dive into Guatemala's Accessible Active Volcano
Just south of Guatemala City rises Pacaya, one of the most active and most visited volcanoes in Central America. Its frequent eruptions, glowing lava, and easy access from the capital have made it a magnet for travellers seeking a close encounter with living volcanism. Yet Pacaya is also a serious hazard to the communities on its slopes, a reminder that its accessibility comes hand in hand with real and ongoing danger.
An active cone near the capital
Pacaya reaches about 2,552 metres and lies within easy reach of Guatemala City, making it one of the most accessible active volcanoes anywhere. After a long period of dormancy, it reawakened in the 1960s and has been frequently active ever since, with Strombolian explosions, lava flows, and ash emissions. Its proximity to a major urban area makes its activity both a tourist attraction and a constant concern.
A magnet for hikers
Pacaya is one of the easiest active volcanoes in the world to visit. Guided hikes climb its forested lower slopes to viewpoints where, during periods of activity, visitors can see glowing lava and feel the heat radiating from fresh flows. The volcano has become a centrepiece of Guatemala's adventure tourism, offering an accessible and unforgettable encounter with an active volcanic system.
The 2010 eruption
In May 2010, Pacaya produced a powerful eruption that sent ash over Guatemala City and the surrounding region, disrupting the international airport and coating the capital in volcanic ash. The event caused damage and casualties and demonstrated that, despite its familiar and accessible nature, Pacaya is capable of significant and dangerous eruptions affecting a wide area.
The 2021 lava flows
In 2021, Pacaya entered a vigorous phase of activity, producing long lava flows that descended its flanks and threatened nearby communities and farmland. The flows destroyed property and forced residents to adapt to the advancing lava, a vivid example of the effusive hazards that this volcano poses alongside its more explosive activity.
Life on the slopes
Communities live close to Pacaya, farming its fertile volcanic soils and depending in part on the tourism the volcano attracts. This proximity means that eruptions, whether explosive ash emissions or advancing lava flows, can directly affect homes and livelihoods. The relationship between the volcano and its neighbours is one of both benefit and risk, closely managed by Guatemalan authorities.
Monitoring Pacaya
Guatemala's volcanology and disaster agencies monitor Pacaya continuously, tracking its explosions, lava output, and ash emissions to provide warnings to nearby communities and to manage access for visitors. Because the volcano is so close to the capital and so heavily visited, effective monitoring and communication are essential to keeping both residents and tourists safe.
A window into Strombolian activity
Pacaya's frequent, relatively mild Strombolian eruptions, characterised by rhythmic bursts of incandescent lava, make it an excellent natural laboratory for studying this style of volcanism. For visitors, these eruptions offer one of the most reliable opportunities anywhere to witness the elemental spectacle of an active volcano at close, if carefully managed, range.
