About Walpole Bay

Walpole Bay is home to what's believed to be Britain's largest tidal pool: four acres of seawater walled into the chalk foreshore in 1937 and now Grade II listed. Margate built the pool so bathers could swim at any state of the tide on a coast where low water can sit hundreds of yards out. Walls of one-ton concrete blocks, laced with recycled tram rails, enclose a stretch about 137m long, with four flights of steps and iron handrails leading in. The sea covers and refills it at every high tide, and freshwater springs rise through the pool floor. Local swimmers, loosely organised as the Walpole Bay Swimmers, use it all year round.
Walpole Bay is also a proper low-tide beach in its own right. As the water drops, the bay's chalk reef — part of the protected Thanet Coast — opens up into rock pools on either side of the tidal pool, with gently shelving sand behind it.

Who visits

You'll mostly find year-round sea swimmers here, doing widths of the tidal pool between tides, along with rockpoolers on the chalk reef at low water and walkers on the promenade path towards Botany Bay.

Swimming conditions and safety

Water quality

Good

Tide and currents

There are no lifeguards at Walpole Bay. The tidal pool deepens from under a metre at the landward wall to about 2.1m at the seaward end; swim it from mid to low tide, as the sea covers the walls at high water and can get rough.

Lifeguards

No lifeguard cover on this beach

Hazards

The concrete walls that lead out to the steps of Walpole Bay's tidal pool are often slick with seaweed, so take them slowly. At every high tide the sea covers the walls completely.
