You can book various organized activities via getyourguide. 

For example dolphin watching, a day trip to Tangier Morocco, a day trip to the Alhambra Granada , the rock of Gibraltar, walking along the Caminito del Rey… you name it. But many of these activities can also be organized yourself, because if you are lucky you can spot dolphins in the sea from the beach of Nerja. What’s also nice is a cycling tour with a student in the city of Malaga along the sights.
