Tar still oozes through the brickwork of this bitumen spring, accidentally struck by 18th century miners.
One of the great curiosities of the Gorge
Don’t miss one of the Gorge’s more curious tourist attractions – an eerie brick-lined tunnel dug into the hillside.
Stand at the entrance to the tunnel and see the treacle-like bitumen oozing through gaps in the walls.
We are sorry that you can’t walk along the tunnel at present, but you still get a view along part of it’s length from the entrance.
