"Know as the darky locally and for good reason. If you do decide to take a walk down this tunnel remember your torch, and I'd recommend one better than your phone. The path is narrow and the sides are fairly low so mind your head as you walk."

"It's dark and scary and the path is really narrow, BUT VERY EXCITING to walk along as part of the chirk to trevor basin canal walk. It's gorgeous and magical with so many surprises along the way namely the aqueduct the visitors centre the activity round the basin. Dreamy, idyllic, heavenly bliss and I did it in the pouring rain."
