Saltfleetby-Theddlethorpe Dunes NNR

Saltfleetby–Theddlethorpe Dunes stretches for 8 km along the north-east coast of Lincolnshire.

saltfleetby - Theddlethorpe Dunes

County: Lincolnshire

Main habitats: Coastal

Area: 952 ha

The reserve's constantly changing habitats include saltmarsh, foreshore and embryonic dunes on the seaward side and the more stable established dunes and marsh on the landward side.  Both are home to a wealth of plants, birds and insects.


The site can be enjoyed all year, although there are some recommended visiting times: May-June for dune flora, May-October for migrant birds, and the winter months for wildfowl.

Natural England organises many events at the Saltfleetby-Theddlethorpe Dunes, including nature rambles, bird walks and activities for children (some suitable for wheelchair users). These events are free and pre-booking is not required.

Horse riding

Horse riding is on the open beach, by permit only.


Dogs are welcome but please keep them on a lead or close at heel at all times. A dog running loose, beyond control can disturb grazing stock and breeding or wintering birds. Please pick up after your dog and place bag in one of the dog fouling bins provided in the car parks.
