It is divided in two by the Río Tírica, with the northern section being both larger and higher.
The massif is notable for its high species richness and for its varied habitat types.
It reaches an elevation of 2,698 metres (8,852 ft)on its highest peak, Murey-tepui (also known as Euroda-tepui).
The massif is situated entirely within the bounds of Canaima National Park. It hosts extensive cave systems, including the world's largest known quartzite cave, Cueva Charles Brewer, named after discoverer Charles Brewer-Carías. The processes behind their speleogenesis are the subject of some debate.
The isolated southern peaks of Andakasimá-tepui and Upuigma-tepui are sometimes considered part of the Chimantá Massif.
