With some terrific day trip options in the surrounding area, renting a car makes good sense. Without one, it wouldn't be half as easy to enjoy everything that Santillana del Mar, 20 miles away, has to offer. Caves of Altamira, Santillana del Mar Zoo and Collegiate Church of Santillana del Mar alone make the drive out worthwhile. Don't forget about Castro Urdiales either! Just 25 miles away, Orinon Beach, Brazomar Beach and Santa Maria Church are non-negotiable stops here.
