Volcan Pacaya: a living volcanic landscape in Escuintla

Volcan Pacaya in Escuintla, Guatemala, is an active volcanic complex whose dark slopes and fresh lava fields give travellers a direct view of a landscape shaped by fire. Rising to around 2,552 m (8,373 ft) above sea level, it forms part of Pacaya National Park and stands on the southern rim of the Amatitlán caldera in southern Guatemala.

The profile of an active Guatemalan volcano

Volcan Pacaya is a complex volcano made up of overlapping cones and domes, built by repeated eruptions over tens of thousands of years. Geological studies place its formation at about 23,000 years ago, making it a relatively young feature within the Central America Volcanic Arc.formed about 23,000 years ago The volcano rises to an elevation of roughly 2,552 m (8,373 ft), though some catalogues give a slightly higher summit figure of 2,569 m (8,428 ft), reflecting differing measurement points along its ridge.elevation of 2,569 m

Pacaya stands south of Guatemala City, on the boundary between the Escuintla and Guatemala departments, within a protected area administered as Pacaya National Park.within Pacaya National Park The national park extends over more than 1,000 hectares, covering both the volcanic slopes and the adjacent Laguna de Calderas basin, where older caldera structures and forested terrain frame the active cone.Pacaya National Park and Laguna de Calderas

Lava, cones and the Amatitlán caldera

The wider Pacaya volcanic complex sits on the southern rim of the Amatitlán caldera, a larger depression created by earlier explosive eruptions, and includes older stratovolcano structures and younger basaltic cones.older stratovolcano with domes The active cone, known as the MacKenney crater, rises from a field of earlier lava flows and tephra deposits, with flanks built predominantly from basalt and andesitic basalts, and with dacitic lava domes forming part of the surrounding structure.basaltic to intermediate melt

Over time, Pacaya has produced a variety of volcanic features that remain visible in the landscape. Short lava flows radiate from the summit area, overlapping older deposits and forming rough, blocky ground on the higher slopes. Pyroclastic layers of ash and lapilli, built up over many eruptions, can be seen where paths and gullies cut through the slopes. The relationship between the active cone and the broader Amatitlán caldera adds a second scale to any visit: the younger central cone rising from within a much older volcanic basin.

A long record of eruptions

In historic times, Pacaya has erupted frequently. Written records from the sixteenth century onwards count at least 23 eruptions since 1565, with more detailed modern monitoring raising the total recorded activity to well over 30 separate events.erupted at least 23 times36 recorded eruptions Activity ranges from mild strombolian bursts and small lava flows to more explosive events that send ash plumes up into the atmosphere, sometimes high enough to affect surrounding towns and air traffic.

Pacaya’s more recent eruptive phases include sequences of strombolian eruptions, lava fountaining and effusive lava flows from the summit crater, described over decades of observation in regional monitoring reports and scientific catalogues.strombolian activity and lava flowsStrombolian eruptions and ash plumes The Global Volcanism Program lists a last known eruption in 2021, continuing Pacaya’s reputation as one of Guatemala’s persistently active volcanoes.

Visiting Volcan Pacaya: what travellers from Western Europe should know

• Volcan Pacaya lies in southern Guatemala within Pacaya National Park, on the boundary between Escuintla and Guatemala departments. Access by road runs south from Guatemala City along the CA-9 highway towards San Vicente Pacaya.
• The standard approach on foot begins near the village of San Vicente Pacaya, where paths climb through farmland and forest before reaching steeper volcanic terrain of loose ash and rough lava.
• The slopes include sections of uneven volcanic rock and ash underfoot, and parts of the ascent traverse exposed ground above 2,000 m (6,562 ft), so visitors should expect sustained gradients rather than short, level walks.
• The official language is Spanish and the currency is the Guatemalan quetzal.
• Entry requirements depend on your nationality; UK travellers can check the FCDO travel advice at gov.uk/foreign-travel-advice, Irish travellers the Department of Foreign Affairs at ireland.ie.

Frequently asked questions about Volcan Pacaya

Where is Volcan Pacaya located?

Volcan Pacaya stands in southern Guatemala within Pacaya National Park, on the border between Escuintla and Guatemala departments, south of Guatemala City.

What should visitors expect on a visit?

Visitors encounter volcanic slopes of ash and hardened lava, with hiking routes that climb from farmland and forest into higher, more exposed terrain near the active cone.

What makes Volcan Pacaya distinctive among Guatemala’s volcanoes?

Pacaya combines a geologically young basaltic cone, an ongoing record of eruptions and a setting on the rim of the Amatitlán caldera, giving it both active and ancient volcanic features in one landscape.
