A dry limestone gorge in the heart of the Mendip Hills and which is now a nature reserve.
There are craggy limestone outcrops, scree slopes, lush wooded valleys and evidence of human inhabitation dating back to Neolithic times.
This is the view from the top of the gorge, looking south over the Somerset levels, which 6,000
years ago was an area of swamps criss-crossed by narrow wooden footpaths supported on underwater poles.
The levels were originally drained by Dutch engineers in the 17th century, but in 2014 hundreds of residents suffered devastating floods covering 20% of Somerset because the Environment Agency had stopped dredging the rivers, preferring to spend £20million on a coastal nature sanctuary instead.
