Salts Hole
From water’s edge to treetopwe’re taking care
When the tidal waters formerly passed through the marshes that you see today, one of the main inlets was here at this small pool, Salts Hole. It was cut off from the sea when the sand dunes developed in the Middle Ages, thus isolating the pool from the sea. Thanks to saltwater seepage the water that collects here remains unusually salty, hence its name


Scientifically it is a feature known as a saline lagoon, a habitat that is decidedly rare in East Anglia. Due to its uniqueness, it is home to a variety of specialist invertebrates such as cockles, periwinkles and shrimps that are found in few other places. Whilst these are unlikely to be seen by the passer by, the birds that congregate here to feed can be. These include Little Grebes, Gadwall, Coot, Goldeneye and occasionally a Kingfisher perched on branches around the perimeter.
