With some great road trip options available in the surrounding area, renting a car makes sense. Without one, it’d be much more difficult to soak up everything that Santillana del Mar, 20 miles away, has to offer. Explore the area starting with Caves of Altamira, Santillana del Mar Zoo and Collegiate Church of Santillana del Mar. Located 25 miles away, Castro Urdiales is another place to aim for. If you drop by, be sure to check out Orinon Beach, Brazomar Beach and Santa Maria Church.
