Fuerteventura is the oldest island in the Canaries, dating back to 20 million yearsago. The last volcanic activity in Fuerteventura was between 4,000 to 5,000 years ago. Most of its interoir consists of arid dunes and rocky mountain ridges, reminiscent of western sahara. Most of the tourists stick to the coast where the fine sandy white beaches are irresistable to sun worshippers.
