The Rock of Guatapé also known as the Stone of El Peñol, or simply La Piedra or El Peñol, is a landmark inselberg in Colombia. It is located in the town and municipality of Guatapé, Antioquia. The town of El Peñol, which borders Guatapé, has also historically claimed the rock as their own and thus the monolith is sometimes referred to as the "Stone of El Peñol" instead of the "Rock of Guatapé".
The landform is a granitic rock remnant that has resisted weathering and erosion, likely as result of being less fractured than the surrounding bedrock. Peñón de Guatapé is an outcrop of the Antioquia Batholith and towers up to 200 meters (656 feet) above its base. A stairway has been carved into the northern face.The 650-foot tall rock was first climbed in 1954 by a group of friends who, over five days, wedged boards into the rock’s large crack. Now visitors can scale the rock via 649 zigzagging stone steps and then be rewarded with a breathtaking view from the summit.
