Lanzarote, is a dry and fairly flat island which owes its eerie landscape to the activity of long since dormant volcanoes. The volcanic ash and craters have now been turned to the islanders’ advantage is a novel method of vine cultivation. The capital, Arrecife, is on the southeast coast and in the area of flattest land on the island. Places of interest on Lanzarote include Teguise (the old capital), with the Guanapay Castle set on a volcanic cone, the oasis-like Haria, Malpais de la Corona, where an immense volcanic cave called Los Verdes, 6km (3.5 miles) long, is located, and the nearby Jameo del Agua lagoon. The National Park of Timanfaya is a spectacular stretch of lava which covers nearly a third of the island and is awe-inspiring in its majesty and barrenness. The most popular excursion is to the volcanoes on camels.
