The Guyana block, south of the Orinoco River in the state of Bolivar, is home to one of the oldest geological formations on Earth, the tepuis. These abrupt plateaus with vertical walls and flat peaks not only define the landscape of the national park as pleasant, but also constitute authentic "eco-islands" dependent on time.
