The Rock of Guatapé, also known as La Piedra del Peñol, rises imposingly in eastern Antioquia, about 70 kilometers (43 miles) from Medellín. Its majestic presence makes it one of the most photographed landscapes in Colombia. Standing 200 meters (656 feet) tall, this gigantic granite monolith towers above the reservoir, offering an incomparable panoramic view.
Formed millions of years ago, the Rock is an inselberg—an isolated hill composed of hard rock that resisted the erosion of the surrounding terrain. Its structure is made mainly of quartz, feldspar, and mica, minerals characteristic of the Antioquia batholith.
