After arriving and settling in at your accommodation of choice, you might want to venture out and explore. If you're eager to check out the beaches, head to Comillas Beach or Oyambre Beach for some relaxation by the water. Make time for a range of local attractions, which include Cabarceno Natural Park and National Museum and Research Center of Altamira. For additional things to see and do, consider a visit to Caves of Altamira or Santillana del Mar Zoo.
