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 👍.

The bridge is new. The circular path and Merlin's cave are great if you like legends

"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!

While Lesnewth itself doesn't have prominent named caves, the surrounding North Cornwall area offers several fascinating options. These include the legendary Merlin's Cave at Tintagel, the impressive former slate mine of Carnglaze Caverns, and the dramatic sea caves along the Boscastle coastline. Additionally, the unique geological formation at St Nectan's Glen offers a different kind of natural wonder.

A carving of Merlin's face can be found near one of the entrances, adding to its mystical appeal. Please check tide times carefully before visiting.
The best time to visit Merlin's Cave is during low tide, as it becomes fully accessible. Even at low tide, there can still be water inside, so be prepared for wet conditions. Checking local tide tables before your visit is highly recommended.

It's an all-weather attraction with a constant temperature of 10°C, providing a unique insight into Cornwall's industrial heritage. Merlin's Cave can also be an exciting adventure for families at low tide, though it involves navigating uneven, wet surfaces.
Merlin's Cave at Tintagel is famously linked to the Arthurian legend, believed to be where the wizard Merlin resided. Carnglaze Caverns showcases Cornwall's rich mining heritage, being a former slate mine active for over 300 years.
