The Helford Pool is a natural pool in the Helford river where it narrows between Helford village and the Helford Passage. It is best dived just after high water on a spring tide. This increases the chance of better visibility and creates an exhilarating drift dive, out of the pool and into the estuary. Starting the dive at the west end of the pit, the drift will slowly take you to the east end where it will force you out into the shallows, past Maerl beds, and, depending on whether you swim north, east or south, you’ll end up in the Bone Yard, the Voluntary Marine Conservation Area or the Oyster Farm.
Over the years, lots of bits and pieces have ended up in the pool. Bottles of all ages are very common.
