The Wash is the biggest bay in England running from just south of Skegness to Hunstanton.
This is one of the most outstanding coastal wetlands in Europe with its bleak, yet beautiful landscape of saltmarshes, mudflats and open water.
The intertidal mudflats and saltmarshes are one of Britain's most important winter feeding areas for waders and wildfowl.
Large numbers of migrant birds such as grey plovers, dunlins, oystercatchers and godwits arrive in the autumn to feed on the rich supplies of foods found in the sands and mudflats.
The best time to see large flocks of waders is on a rising tide between September and early May.
The area is also a breeding ground for Atlantic grey seals.
The Wash National Nature Reserve is accessible by the Peter Scott Walk. Many sites away from the footpath on the sea wall are extremely dangerous and should only be explored with an experienced local guide.
The Wash has a number of other habitats of conservation significance, including saline lagoons, shingle structures and dune complexes.
Safety - keep to paths and do not stray into areas where they may be quicksand and dangerous tidal conditions. Visitors are advised to stay on the seawall.
