This is a small ferry ride from virtually the centre of Santiago de La Ribera (at the the Nautica) to the Tomás Maestre Marina, on the La Manga side of the Mar Menor. But you arrive some 15 kilometres from the centre of La Manga and, unless you take a bycilce, there is not too much to do. There are plenty of small bars and restaurants dotted around the port, but it is not the busy "downtown" La Manga. You can choose to relax in the waters of the Mar Menor or, with a walk, dip into the Mediterranean See side. The ferry is not a fast and there is time to have a beer or two on board, which are sold on board. A fun thing to do if you have some spare time.
One way trip: 5€. Bycilcles: 1€
