From hidden coves to long, wide strands, lovers of sand and surf will be deliriously happy on Tenerife - and in fact, your greatest problem will be choosing between them. The most popular is Las Teresitas in Santa Cruz, which is a particularly good option for families, with its fine golden sand and calm waters sheltered from rough surf. In this same area you'll also find black-sand Las Gaviotas, especially impressive because of its surroundings. But it's in the south of the island where you'll find the most attractive beaches of all. Los Cristianos in Arona is one of the most famous, and if you head toward the Golf del Sur golf course you'll come across little coves that can be a bit tricky to get to but are hard not to fall in love with. From here, heading up toward Santa Cruz you'll encounter El Roque and El Puertito, surfer magnets with spectacular views of the Atlantic.
