Lots of wide pavement around the water, wasn't too busy on a Sunday afternoon but I imagine it gets rammed with people sometimes.

Great road for cycling up/down. The surface has degraded a bit over recent years, but still a great climb/descent.

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.
