The White Cliffs of Dover rise to 110 metres above the busiest shipping lane in the world, and the National Trust looks after the stretch east of the port from its visitor centre at Langdon Cliffs, where a well-kept path leads out to the classic view over the ferries and, on a clear day, across to France. The chalk grassland is grazed by Exmoor ponies and cattle and is rich in wildflowers and butterflies in summer. The clifftop walk runs about two miles to South Foreland Lighthouse, passing Fan Bay Deep Shelter, a Second World War tunnel complex toured in hard hats and head torches with guides; allow around forty minutes each way. Reviewers praise the signposting, the clean cafe with seating inside and out, and the fresh scones at the lighthouse tearoom. Tips from visitors: the coastal paths narrow and get uneven in places, so keep young children and dogs close, wear proper walking shoes, and use the boot wash by the car park on muddy days.
