The landscape on Bartolomé is made up of real volcanic desolation; tuff cones, spatter cones (cones formed of molten lava ejected from a vent), scoria formations (formations of highly vesicular, dark volcanic rock) and black volcanic sand. We follow the 600 meter pathway (made up mostly of stairs) to the summit, which stands at a height of 114 meters. From the summit is the breathtaking view of Bartolomé island, Pinnacle Rock, Sullivan Bay and Santiago Island.
Pinnacle Rock, featured in the movie Master and Commander, is one of the most distinctive characteristics of Bartolomé island and the most representative landmark of the Galápagos islands. This rock is the last remaining piece of an eroded tuff cone. It is thought that its distinctive shape could also have been created by the American pilots, based on nearby Baltra Island in World War II, who used Bartolome for target practice.
