Popularly known as "the Fire Mountains," this national park takes up much of southern Lanzarote. As you enter the park from Yaiza, the first thing you'll see is the staging area for the Canaries' best-known camel rides. A bumpy camel trek lasts about 20 minutes. The volcanic landscape inside Timanfaya is a violent jumble of exploded craters, cinder cones, lava formations, and heat fissures. The park is protected, and you can visit only on a bus tour. A taped English commentary explains how the parish priest of Yaiza took notes during the 1730 eruption that buried two villages. He had plenty of time—the eruption lasted six years, making it the longest known eruption in volcanic history. By the time it was over, more than 75% of Lanzarote was covered in lava. Throughout the park, on signs and road markers, you'll see a little devil with a pitchfork; this diablito was designed by Manrique.
The Ruta de los Volcanes bus tour takes you around the central volcanic area on a 14-km (9-mile) circuit that was designed to have minimal impact on this natural park. Tickets can be bought at the stand at the entrance to the national park. During summer, visit in late afternoon to avoid the crowds.
