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.

Also referred to as Black Mountain Quarry, Herbert's Quarry ceased operation in the late 1950s and since then its buildings have fallen into ruin. The remains and spoil heaps tell the story of 200 years worth of lime burning and the production of quicklime for agriculture.

South Wales' westernmost 2,000-footer at 2,021 feet (616 m), Garreg Lwyd is the last high outpost of the Black Mountain range. It makes for a very quick ascent from the A4069 road, where you can also explore the quarry workings, pits and lime kilns of Herbert's Quarry. Garreg Lwyd is also easily linked with Foel Fraith, its slightly smaller sibling to the east.

The towpath that runs along the Swansea Canal is a gorgeous leafy stretch that makes for great access to the city from the north avoiding the roads and traffic. You can either walk or cycle on the towpath, which occasionally switches over the river on a series of narrow bridges. Do take care if you're on a bike as there's often runners, walkers, children and dogs also using the shared path.
