Herbert’s Quarry is part of the Black Mountain and Mynydd Myddfai Registered Landscape of Outstanding Historic Interest in Wales. Unlike in other lime producing areas where canals and tramroads could be built, the industry at Herbert’s Quarry was served solely by road transport. The lime trade was a factor in the development of Turnpike roads, and the network of tracks and roads over the mountain is closely associated with the activity at Herbert’s Quarry. As you walk through the site you are taking a journey through time, and walking in the footsteps of many hundreds and thousands of people before you, people whose hard work, sweat and drudgery shaped this landscape and left a rich industrial legacy.

NCN43 follows old railways lines, riverbanks and canals from Swansea to Clydach. This section follows an old railway line, it's flat and gravelled, easy riding but pretty and no cars.

Nice gravel track down to the reservoir with lovely views. Track down can get muddy but good fun. Do-able on a gravel bike

Easy walking along the Eastern and Southern edges of the reservoir, courtesy of the Gower Way (a 35-mile path linking Penller Castell to Rhossili if you fancy stretching your legs a little further). Fantastic views.
