Laguna de Ayarza

Laguna de Ayarza is a crater lake located in the Santa Rosa department of Guatemala, formed within the caldera of a volcanic explosion. The water body lies in a steep-sided basin and is known locally for its scenic setting and recreational use.

Visitors typically approach the lake from nearby towns and use the shoreline for swimming and fishing; the lake is part of the local rural landscape rather than a large national park. The surrounding terrain is volcanic, with agricultural land and scrub on the lower slopes.

The lake occupies a volcanic crater created by a major explosive event in the geological past; sediments and local studies indicate a volcanic origin rather than a tectonic basin. Contemporary use is recreational and local rather than large-scale tourism.

Laguna de Ayarza sits in southeastern Guatemala’s volcanic highlands within Santa Rosa department, surrounded by agricultural countryside and smaller settlements.

From Guatemala City: drive southeast along CA-9/CA-1 then take local roads toward Barberena and the town of Casillas; the lake is about 90-120 minutes by car depending on route and traffic. Local colectivos and drivers in nearby towns can arrange shorter transfers to lakeside points.

• Combine a visit with exploration of nearby haciendas and the small lakeside towns to see how locals use the lake for fishing and recreation.
• Swim cautiously: the lake is warm compared with Andean lakes, but currents and depths can be unpredictable.
