Donna Nook National Nature Reserve covers more than 10 km (6.25 miles) of coastline between Grainthorpe Haven in the north and Saltfleet in the south where it borders the Saltfleetby-Theddlethorpe National Nature Reserve.

Grey seals

For much of the year grey seals at the Lincolnshire Wildlife Trusts’ Donna Nook National Nature Reserve are at sea or hauled out on distant sandbanks. Every November and December, the seals give birth to their pups near the sand dunes: a wildlife spectacle which attracts visitors from across the UK. 

The Viewing Area - open late October to December

The viewing area at the foot of the sand dunes reduces disturbance to the seals and ensures the safety of visitors. Visitors should be aware that the Ministry of Defence still maintains part of the area as a bombing target range. The seal viewing area is accessible at all times.
