Porthtowan’s Hidden Mermaid Pool: Cornwall’s Secret Sea Swim
A Century-Old Secret Nestled Below the Cliffs
If you’ve walked Porthtowan Beach without spotting the Mermaid Pool, you’re in good company—most visitors have no idea it exists. This enchanting saltwater tidal pool, carved into the rocky eastern flank of one of Cornwall’s most beloved Blue Flag beaches, is a hidden gem that locals have cherished for over a century.
The pool’s story is as captivating as its appearance. In 1908, visionary Francis Beringer gained permission from the Prince of Wales to construct this natural bathing sanctuary using Cornish mining explosives and relocated cliff-base boulders. The ingenious concrete wall design captures seawater perfectly at low tide, creating a sparkling azure lagoon that disappears entirely when the ocean returns.
What makes the Mermaid Pool truly special is how it remains virtually invisible to the casual beachgoer. The dramatic cliffs tower above, and the rocky terrain keeps it secluded and intimate. Whether you’re planning to visit Newquay for its famous surf spots like Fistral Beach or exploring quieter corners of our coastline, this tidal pool represents the kind of authentic local discovery that makes our North Coast exceptional. For those willing to scramble over barnacle-covered rocks and time their visit carefully, the reward is unforgettable.
Planning Your Visit: Timing and Safety Matter
Reaching the Mermaid Pool requires knowledge and respect for the tides—this isn’t a casual stroll. The crucial rule is simple: visit within two to three hours of low tide on either side. Plan your visit with a tide table in hand, and you’ll find yourself in a magical swimming sanctuary. Arrive at the wrong time, and the pool simply vanishes beneath the waves.
Access has become increasingly challenging over recent years. The old cliff-path steps have deteriorated dangerously due to coastal erosion and rock falls, making them completely off-limits. Your safest approach is from the northern side at low tide, keeping the concrete wall visible as you carefully navigate the rocky terrain.
Robust footwear is absolutely essential—the rocks are covered in sharp barnacles that will shred regular trainers and skin alike. If you’re bringing children or pets, exercise particular caution. The unforgiving rocky surface demands sure-footedness and good judgment. Summer dusk visits or sheltered winter swims offer the best chance of solitude, as school holidays and sunny spells bring larger crowds. Local knowledge proves invaluable here; chat with beachside café staff or accommodation owners about current conditions before attempting your descent.
Porthtowan Beach: Your Gateway to Coastal Adventure
Porthtowan Beach itself is a destination worth exploring beyond the Mermaid Pool. This consistently Blue Flag-awarded beach since 2005 offers something for everyone—from serious surfers tackling excellent swells to families enjoying the gentler sandy stretches bordered by dramatic cliff faces. The crystal-clear waters and well-maintained facilities make it genuinely welcoming.
When you go to Newquay to catch the renowned Fistral Beach waves or explore other North Coast spots, consider making Porthtowan your adventure base. Nearby shops cater to every beach need, while the friendly community atmosphere sets it apart from busier tourist hotspots. If you’re staying locally, seek out dog friendly accommodation so your four-legged companions can enjoy beach time too—many local B&Bs welcome pets warmly.
The beach’s infrastructure supports quality visits without overwhelming the landscape.
