Cornwall's Secret Mermaid Pool: A Hidden Tidal Lagoon on Porthtowan Beach
Nestled along the rugged North coast of Cornwall, a breathtaking secret awaits discovery at one of the UK's most celebrated beaches. The Mermaid Pool, a hidden tidal lagoon at Porthtowan Beach, remains largely unknown to visitors, offering a mesmerising and magical swimming experience for those who uncover its location amongst the rocks.
The History and Creation of the Mermaid Pool
This remarkable tidal pool boasts a fascinating history dating back to 1908, when local resident Francis Beringer obtained permission from the Prince of Wales to construct the pool. The sole condition was an annual rent of just one shilling to be paid to the Duchy of Cornwall land steward.
Built with assistance from Cornish mining explosives specialist Jabus Foster Maynard, enormous rock boulders at the cliff base were repositioned to create a concrete dam that naturally holds seawater as the tide retreats. Vintage photographs from the 20th century capture the pool in its full splendour, with locals recalling it retained water more effectively in years gone by.
Finding and Accessing the Hidden Lagoon
Tucked away amongst rocks beneath the cliffs on Porthtowan Beach's eastern side, the Mermaid Pool remains completely concealed from unsuspecting visitors. The waters are replenished by incoming high tides, making low tide the ideal time to experience this stunning coastal retreat.
Important safety considerations:
- The original cliffside steps have become too dangerous due to erosion and rockfalls
- The safest approach is from the north at low tide, keeping your back to the sea
- Sturdy footwear is essential for navigating barnacle-encrusted rocks
- Extra vigilance is required when bringing children or dogs
- The optimal swimming window is within two to three hours either side of low tide
Porthtowan Beach: More Than Just a Hidden Gem
While the Mermaid Pool remains a secret, Porthtowan Beach itself is far from hidden. Consistently regarded as one of Cornwall's finest beaches, it has proudly held the coveted Blue Flag award since 2005, recognising its environmental standards, amenities, and overall quality.
Key features of Porthtowan Beach include:
