Set sail past Gran Canaria's rugged volcanic landscapes as you glide along the coast on this four-hour trip. Pop some fins and a mask on and dive into the clear waters of a secluded bay to spot native rays, octopuses and colourful parrotfish. Make the most of the water with the paddleboards and water slides provided, then relax on the sun deck. There's an open bar, stocked with cava, beer and soft drinks, to wash down a Canarian meal of paella, salads and fruit, too.
