Sarstoon River (Guatemala)

Weather…

The Sarstoon River is an ecologically significant waterway that forms the natural boundary between Guatemala and Belize in the southern portion of the Petén region. Originating in the mountains of Alta Verapaz, it eventually empties into the Amatique Bay in the Caribbean Sea. The river flows through the Sarstoon-Temash National Park area, renowned for its extensive mangrove forests, wetlands, and extraordinary marine biodiversity. This region serves as a critical habitat for endangered species such as the West Indian manatee and the American crocodile. Historically, the river was an important trade route and continues to be a geopolitically sensitive area due to long-standing border disputes between the two neighboring nations. Its banks are lined with dense tropical rainforests that support numerous indigenous communities, particularly the Qʼeqchiʼ Maya. The preservation of this ecosystem is of international importance, as it constitutes one of the best-preserved estuaries on the Central American Caribbean coast. Despite its protected status, the region faces threats from illegal logging and overfishing.
