Petén Basin

The Petén Basin is a broad lowland region in northern Guatemala that was a central area for the Classic Maya civilization. The basin covers much of the modern Petén Department and contains many major archaeological sites, including the UNESCO World Heritage site of Tikal.

Within the basin visitors encounter dense tropical forest and numerous archaeological ruins ranging from monumental city centers to smaller outlying sites; trails and roads link the principal ruins, but many sites remain in forested settings. The region is important for both cultural heritage and biodiversity, with protected areas established around several major ruins.

Historically the Petén Basin supported densely populated Maya polities during the Classic period (roughly 200 to 900 AD) and later experienced political fragmentation and population changes in the Terminal Classic period. In the modern era the basin has seen changes from limited settlement to increased agricultural and forest-use pressures during the 20th century.

Geographically the basin occupies the northern department of Petén in Guatemala, bordering Mexico and Belize, with the major archaeological centers distributed across its tropical lowlands.

• Maya heartland: Contains numerous major Classic Maya archaeological sites, including Tikal, and was a core region for Maya civilization between about 200 and 900 AD.
• Landscape: Features lowland tropical forest and wetlands; many ruins are set within protected parks and reserves and require travel through forested terrain.
