Teide National Park on Tenerife surrounds Mount Teide, the highest mountain in Spain at about 3,715 metres. It is a volcano rising from a huge caldera of lava fields and strange rock formations such as the Roques de García. A cable car climbs near the summit. The clear skies make it a famous spot for stargazing. It is a UNESCO World Heritage Site.

Roque Nublo is a basalt rock about 80 metres tall standing on a summit in the centre of Gran Canaria, at about 1,813 metres. It was formed by volcanic eruptions millions of years ago. It is a symbol of the island and was once sacred to the native Canarians. A short hike leads up to it, with views over the island and to Mount Teide on Tenerife.

Timanfaya National Park on Lanzarote covers a landscape of volcanoes and lava fields formed by eruptions in the 1730s and 1820s. The ground is still hot just below the surface; guides show how dry branches catch fire and water turns to steam. A restaurant grills food over volcanic heat. Visitors tour the park by bus along the Route of the Volcanoes.
