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!

You can go through the cave once at low tide and come out on the other side, but not with dry feet, and only in the "deep" stage at low tide. Very interesting and a bit scary, but a lot of fun.

The cave is open from both sides. If you go inside you can be lucky that the light reflects beautifully in the water. Depending on the water level, you can also climb here.

Are there any hidden coves or beaches with caves to explore?

Yes, Bossiney Cove is a beautiful hidden gem that features a small sandy beach and caves, but it is only accessible at low tide. The access involves a footpath over farmland and then steep steps, making it unsuitable for wheelchairs or those with mobility issues.

What is the best time to visit the coastal caves around St Gennys?

There are also MTB trails and running trails to explore the stunning coastal and inland landscapes.

Are there any family-friendly cave experiences near St Gennys?

While the natural sea caves directly in St Gennys require careful timing and conditions, the accessible parts of Merlin's Cave at Tintagel can be a fascinating experience for families, especially when combined with a visit to Tintagel Castle. Always prioritize safety and check tide times.

What are the geological features of the St Gennys coastline?

The St Gennys coastline is shaped by dramatic cliffs primarily composed of black shale, quartz, and sandstone. This geological makeup, combined with weaknesses like faults and fractures, allows for the formation of sea caves through relentless wave erosion. The area also boasts High Cliff, the tallest cliff along Cornwall's coastline.

Are there any guided cave tours available in the St Gennys area?

Specific guided cave tours for the natural sea caves directly in St Gennys are not widely advertised, as these are undeveloped littoral caves.

However, the area is popular for activities like coasteering and sea kayaking, which can offer opportunities to explore these coastal features with experienced guides.

What should I wear or bring when exploring coastal caves?

When exploring coastal caves, especially those accessible at low tide, it's advisable to wear sturdy, non-slip footwear that can get wet. A torch or headlamp is essential for visibility inside darker sections. Always check tide times and weather forecasts, and consider bringing a waterproof bag for personal items. For undeveloped sea caves, local knowledge or a guided activity is recommended.
