Coastline. Well, you might say, of course there is coastline, England is an island.
But, before the England Coast Path came into view, only one English coastline has a national trail along its length. The South-West Coast Path, at well over 600 miles, is the longest of our national trails, hugging almost every mile of the region.
And a superb coastline it is too, something for everyone, from genuinely rough and remote walking around Hartland Quay or Zennor, say, to quiet sandy bays, impressive industrial and prehistoric archaeology, and thriving seaside resorts.
But what happens if you want something more challenging, navigationally, than making sure the sea is always on the same side of your body? (And before anyone says anything, yes I do know there are navigational challenges on the coast path too.)
You could try Dartmoor. The highest and most extensive moorland in southern Britain, it’s been used for military training for decades, precisely because the disorientating effect of the granite tors puncturing a wild plateau subject to frequent mist and fog poses tests no matter how fit and experienced you might be.
