Sibun River Hills (Belize)

Weather…

The Sibun River Hills are a dramatic and rugged landscape of steep limestone hills located south of the Belize River Valley, primarily within the Cayo and Belize Districts. The powerful Sibun River, known for its flash floods, has carved deep, spectacular gorges and valleys through this karstic terrain. These hills are part of the Sibun Forest Reserve, a large protected area containing extensive tracts of pristine tropical forest. The difficult terrain has limited human activity, preserving the area's wild character. It is a critical watershed and an essential habitat for a diverse array of animal and plant life, including large cats and rare birds. The caves within the hills, such as the famous Crystal Cave, hold significant archaeological value, containing Maya pottery and skeletal remains, indicating their use for ancient rituals.
