Saltfleetby -Theddlethorpe Dunes National Nature Reserve - we understand there are 3 accessible trails suitable for wheelchair users. - "This important reserve contains tidal sand and mudflats, salt and freshwater marshes and sand dunes. On the foreshore, accreting mud and silt flats and saltmarsh in the north give way to a narrower sandy beach at the southern end. The sand dunes are also much wider in the north and there is an extensive freshwater marsh between two dune ridges, which converge into a narrower ridge south of Churchill Lane at Theddlethorpe." "Various routes including an easy access trail with display boards through Rimac" - from the Lincolnshire Wildlife Trust website.
