Explore volcanoes in Lanzarote
This Canary island has plenty of opportunities for adventure. Join a windsurfing lesson, explore huge caves or sign up for a camel safari. But the highlight of an active holiday here is a visit to the Mars-like landscape of the Timanfaya National Park. Translated as The Fire Mountains, it is home to an active volcano and is a perfect place for hiking (excursions from £30, excursionslanzarote.com).
