Porthtowan Tidal Pool

Porthtowan Tidal Pool is a secluded sea pool cut into the northern cliffs of Porthtowan Beach on Cornwall’s rugged north coast. Built in the early 1900s by local landowner Francis Berginger using mining techniques and explosives, the pool features a concrete dam and natural rock walls that trap seawater at low tide, forming a calm and sheltered swimming spot. Accessible via a short rock scramble around low tide, it’s a favorite among wild swimmers and families seeking a peaceful dip away from the surf, with a sandy bottom and clear waters. Open and free year-round, the pool offers a unique coastal experience that requires a short rock scramble to reach, which keeps it quieter than the main beach—just be sure to check tide times and wear sturdy footwear for a safe visit.
