This spot is a real gem! You can get to it from Llanes or Celorio, and the walk is totally worth it - particularly the section of the coastal path that links the two towns. The sand is plentiful at low tide, and there are plenty of caves and delightful corners to explore. At low tide, you can also access the beaches to the right. When you arrive, you'll find a wooden table with seats right by the access stairs.
It's a paradise of natural beauty, so please be sure to treat the environment with respect!
