Thirty years ago only fools or psychogeographers would have set out to walk the coast of County Durham. This was ‘Get Carter’ country, a dozen miles of grim coastline massively polluted by coal mining and pit waste tipping.

After the last of Durham’s coastal pits closed in 1993, a remarkable operation named ‘Turning the Tide’ saw a clean-up of the cliffs, the beaches and the steep wooded valleys called ‘denes’. Following the clifftop path south from Seaham Harbour on a fine windy morning, we couldn’t believe this was the same colliery coast that we’d once known.

Down on Blast Beach the sea is slowly eroding the minestone. Blast Beach got its name from the blast furnaces of the adjacent ironworks which covered the beach with a thick layer of grease and sludge. Mixed with coal waste from Dawdon Colliery, this scab of industrial slag was dubbed ‘minestone’ by locals. It’s a remarkable sight, a flat shelf of pale grey and orange that extends seaward from the feet of the pale magnesian limestone cliffs, to form its own miniature cliff at the high water mark.

We walked Blast Beach, marvelling at the contrast between the barren layer of minestone and the rich flora that has developed under the cliffs – buttery yellow bird’s-foot trefoil, intensely purple bloody cranesbill. Fulmars planed along the cliffs, and nesting kittiwakes looked down on us with eyes as soft and black as pandas.

Up on the cliffs again, we strolled the grassy meadows where bee orchids grew in clumps. On the sheltered beach of Hawthorn Hive a man was collecting waste coal into a sack. ‘Sea coalers’ were a common phenomenon hereabouts when the collieries were in full swing, but there’s little sea coal left today.

Easington Colliery’s beach was once a wasteland where a gaunt gantry dropped a continuous stream of mine filth into a blackened sea. Now it’s a beautiful sweep of pale pebbles on which the waves break in white foam.

Horden Beach was a three-mile swathe of stones and sands, its minestone ledge now sea-nibbled halfway back to the cliffs. From here we struck up the path into Castle Eden Dene, and walked up into Peterlee through a green canopied cleft full of ferns and water-sculpted rocks. Goldcrests squeaked in the treetops, and the underworld below the trees was hazed and smoky with bluebells.
