Donna Nook Coastal Trail

Donna Nook sits on the Lincolnshire coast where the salt marsh meets the North Sea, famous for its grey seal colony that hauls out in large numbers during the autumn and winter pupping season. This 6.4 km out-and-back follows the sea defence embankment with uninterrupted views across the marsh and out to open water. The terrain is flat throughout with just 10 m of climbing, and the going is straightforward on gravel and embankment paths. The landscape is vast and exposed, with big skies and the constant presence of the sea defining the character. Outside seal season the coast is quiet and atmospheric, with wading birds and marsh scent providing the main interest.

This is a dog friendly walk with strong coastal character in a stripped-back landscape. The salt marsh carries intense tidal scent that keeps dogs working, and the open, exposed embankment provides wind and long views. Off-lead potential is moderate along the quieter sections, though dogs must be kept well away from the seal colony during pupping season and under control near the marsh edge where birdlife is sensitive. The flat, firm surface suits dogs of all ages and fitness levels. The exposed nature of the route means wind can be fierce, which most dogs enjoy but owners should dress for. A walk that showcases the raw, wide-open quality of the Lincolnshire coast at its most elemental.
