One of our best days at the Costa Blanca was scooter day! We rented a scooter in Calpe (you’ll find many organizations) and headed all the way to Cumbre del Sol. This route will give you the best views and shows a lot of the region.
Along the way, stop at some beaches for some refreshment. My favorites: El Portet, Calella Granadella (the road to the beach itself is worth it too), Cala Moraig.
