Supping is the chilliest way to be active without breaking down. You stand on your board, paddle past rocks and caves, and with a little luck, a dolphin comes bobbing alongside you. Alone, with your partner or your dog - anything goes. Boards you just rent on the beach, or shop one at Decathlon for the real diehard. The route from Cantarriján to Nerja is a must, but even in a quiet bay it is blissful floating around. Want to bring your snorkel? Always do.
