A tiny but breathtaking tidal pool nestled along Cornwall's north coast is being hailed as one of the country's most cherished treasures. Known as the Mermaid Pool, it is located on Porthtowan Beach yet remains unknown to many visitors outside the local community.
Rightly regarded as one of the 'North coast's best kept secrets', this tidal pool is entirely submerged at high tide, making its appearance at low tide a magical discovery. Built in 1908 by local Francis Beringer with permission from the Prince of Wales, the pool was constructed using large rock boulders and concrete to retain seawater as the tide receded. The sole condition was an annual fee of 1 shilling paid to the Duchy of Cornwall.
Accessing the pool presents challenges. A former set of steps from the cliffs has become too dangerous due to coastal erosion and rock falls. The best approach is from the northern side at low tide, keeping the concrete wall in view. Alternatively, clambering over large rocks from the main beach may be possible, though care is essential. Robust footwear is recommended due to barnacle-covered rocks.
To enjoy a dip, plan a visit within two to three hours of low tide. Locals know the spot, so school holidays and sunny spells draw larger crowds. An evening visit at dusk in summer or a sheltered winter swim may offer a quieter experience.
Porthtowan Beach itself is a popular destination, especially for surfers, and has held the Blue Flag award since 2005. At low tide, the beach nearly doubles in size to 1.5 miles, linking with Chapel Porth beneath the cliffs of Wheal Coates tin mine. The surrounding cliffs provide shelter, and rock pools emerge as the tide drops.
