Even at low tide, there is still water in the cave. In some places you can balance along the edge and you may have to take your shoes off. A group played and sang mystical/Celtic music for us. It suited this place perfectly 👍.

"Merlin's Face" The carving was completed in February 2016 by local craftsman Peter Graham, who described the work as a "temporary intervention" that would be eroded by the weather. Mr Graham hoped the carving would capture people's imagination and said he had received "overwhelming support" from visitors to the site.

How much poorer would European literature be if he didn't exist: MERLIN (according to Wikipedia, the Welsh origin of the name is Myrddin or Merddin) is one of the biggest stars in the sky of mythology. Together with the heroic King Arthur, he has conquered a permanent place in the collective memory of people - at least in the fantasy world of countless authors who have told his story over and over again for centuries, and above all in their ever-fascinating readers or listeners. Daniela has already briefly mentioned in her article the historical connection between this hiking highlight with the beautiful name "Merlin's Cave" and the person of the legendary magician. And the main thing is, of course: the myth lives on!
