Timanfaya National Park or Parque Nacional de Timanfaya is a Spanish national park covering the municipalities of southern portion of Tinajo and the northern portion of Yaiza in the southwestern part of the island of Lanzarote. The area is 51.07 km².
The parkland is entirely made up of volcanic soil. The greatest recorded eruptions occurred between 1730 and 1736. The volcanic activity continues as the surface temperature in the core ranges from 100 to 600 ºC at the depth of 13m, which is demonstrated by pouring water into the ground, resulting in a geyser of steam which is an attraction for tourists. In 1993, UNESCO granted the qualification for the Biospherical Reserve.
The statue "El Diablo" by César Manrique is its symbol. The park is open to the public, and conducts tours of the volcanic landscape by coach.
