Who needs a beach when you've got a wonderfully quirky swimming pool complex designed by acclaimed Lanzarote architect César Manrique? For anyone who's nervous of tackling the Atlantic rollers at the town's main beach, Lago Martiánez in Puerto de la Cruz offers a wave free alternative. Slip into your bathing costume and soak up the sun beneath towering palms, then glide across the surface of lagoon sized pools, avoiding fountains whose plumes comes back to earth with the force of hailstones. At night swap the bathing costume for something more sophisticated and have a flutter at the casino below the main pool.
