English: The Galápagos archipelago comprises many larger and smaller islands. They are mostly made of solidified lava from the nearby volcano, a slippery surface at high tide. 90% of the area belongs to the National Park of Galápagos (Ecuador). Wildlife preservation is mandatory, which can be seen at the Charles Darwin station. Visitors pay an entrance fee and are encouraged to be extremely careful and observant towards the iguanas, red crabs, sea lions, fregate birds, flowery bushes, giant turtles and other forms of native flora and fauna.
