Pacaya, Active volcano in Escuintla Department, Guatemala.

Pacaya is an active volcano in Escuintla Department, Guatemala, rising to 2552 meters (8373 feet) as part of the Central American Volcanic Arc. Multiple craters mark its summit, from which continuous plumes of smoke rise, while solidified lava flows descend the flanks and form a barren lunar landscape.

After 70 years of rest, the volcano began a new phase in 1961 with repeated eruptions that continue to this day. Major eruptions in the 1960s changed the shape of the summit and forced people in surrounding villages to relocate.

Pacaya lies within Pacaya National Park, declared on 20 July 1963, and the park's income comes from tour groups entering the reserve. The 2010 eruption left a lava field that the Guatemala Impact Marathon later used as a running route, with runners supporting nearby communities. Volcano boarding is practised on the craters.

Access to the national park costs 100 quetzales, and hikers should check current conditions via INSIVUMEH before starting the climb. Sturdy footwear and warm clothing are advisable, as wind and cool temperatures prevail near the summit, even though the approach begins in tropical heat.

At certain spots on the slopes, heat from volcanic fissures reaches temperatures sufficient to roast or cook food. Some guides show visitors these natural oven sites and prepare marshmallows or small snacks there.
