These tunnels are a notable part of the history to and from the Abercwmeiddaw Slate Quarry. In 1864, an experimental tunnel machine, designed by John Dickinson Brunton, this tunnelling machine was one of the minor few machines to even once exist and that was Worldwide! This tunnelling machine, was powered by a steam engine and was used to bore huge 80m circular tunnel and a failed 10m tunnel that both were drilled deep into the rock. However despite John Dickinson Bruntons efforts in him aiming to revolutionize quarrying. While yes he’d been very successful within these bored tunnels and had success in creating the quarried tunnels, yet the bore machine itself was far, far too difficult to even control and the whole operation was abandoned.

The binoculars tunnel is something quite unique and can be reached relatively easily if you have good footwear, take care, and don't mind a short scramble. This place is not suitable for small children though.

Site of Special Scientific Interest (SSSI): Coed y Gopa is designated as an SSSI due to its exceptional biological interest. Bats: It's particularly renowned for being home to the second largest lesser horseshoe bat hibernaculum in North East Wales. These bats utilize the numerous old mine workings (adits) and natural caves within the site for winter hibernation. Other bat species like Natterer's bat and Daubenton's bat are also found here. The wide rides and varied habitats within the wood provide excellent feeding areas for bats. Other Wildlife: Beyond bats, the woodland supports a rich array of wildlife, including various bird species like ospreys, goshawks, pied flycatchers, redstarts, and wood warblers.

Highly recommended for a stop variable activities and pursuits to undertake as so many walking activities and routes to explore the children’s Playground my boy and friends loved the most as given its winter hours not a lot was actually available and open to public use also toilet facilities are limited in winter months cafe open but be sure to check the times upon arrival.
