Timanfaya National Park (Parque Nacional de Timanfaya)

A 51.07 km² national park established in 1974, encompassing the Montañas del Fuego (Fire Mountains) created by volcanic eruptions between 1730 and 1736 — the longest recorded volcanic event in history, covering approximately one quarter of the island in lava. The landscape is otherworldly: a vast expanse of solidified lava fields, volcanic cones, and ash deserts in hues of red, black, orange, and ochre. Geothermal activity persists just metres below the surface — park staff demonstrate this by pouring water into boreholes, which erupts as steam within seconds, and by igniting dry brush placed in a shallow pit. The 14 km "Ruta de los Volcanes" coach tour (included with entry) winds through the most spectacular sections. The El Diablo restaurant, designed by César Manrique, uses geothermal heat to cook food. Arrive before 10:00 AM to avoid long queues. Entry fee applies.
