Adventurers flock to Wales for countless experiences, with the stunning nation offering endless possibilities; nevertheless, one Welsh explorer recently stumbled upon a breathtaking find – and it follows shortly after his exploration of a deserted farmhouse. Dan, recognised by his online community as the Welsh hiker, has gained acclaim for recording his treks and remarkable discoveries throughout Wales, but his most recent find left him utterly astounded.

In a fresh TikTok clip, he revealed how he encountered Dinorwic Quarry (alternatively called Dinorwig Quarry), which stands as a massive former slate quarry, positioned between the settlements of Llanberis and Dinorwig in Gwynedd. Dinorwic Quarry (Chwarel Dinorig), which towers above Llyn Peris and Llyn Padarn, previously ranked as the globe’s second-largest slate quarry, functioning from 1787 until 1969, as stated by Wales Slate.

Whilst physical traces of its history endure, Dan explained the location has transformed into a favoured destination for rambling and rock climbing. However, fury has erupted in the town recently over the number of tourists it attracts. 

Dan lately posted footage of his site exploration online, declaring that viewers would struggle to believe what exists within. Despite remnants of its heritage persisting, he described the views as absolutely magnificent.

According to Dan, the location provides “stunning views of the surrounding mountains and lakes”, and examining the footage clearly demonstrates why he wished to showcase its splendour. The video has garnered dozens of likes and several comments, with viewers praising the “beautiful” views it offers.

One viewer commented: “Amazing video of a very special place.” Another chimed in with: “Great place to explore. You could spend hours there.”

A third viewer noted: “And the goats are blinkin’ massive.” To which Dan responded: “Massive but cool.” The quarry, operational from 1787 to 1969, boasts over 30 galleries or terraces, each connected to a rubble tip. These are also linked to one of the inclined railway systems, a notable feature of the quarry.

After the site’s closure in 1969, a company quickly acquired it and developed a hydroelectricity scheme in the area, allowing nearly all the structures to survive. The Australia gallery, housing a large mill building and its electrically powered equipment dating back to the 1920s, is a prime example of this.

Despite Dinorwic Quarry being considered an abandoned industrial site, it isn’t entirely unused. Parts of the site have become a popular destination for activities such as climbing and hiking, and it even houses a power station.

Mining operations ceased in 1969, leaving behind a dramatic landscape filled with ruins, old machinery and railway tracks that highlight the area’s rich industrial heritage. This might explain why so many people find the site fascinating to visit.

Llechi Cymru, speaking on the safety of exploring the site, said: “The Slate Landscape of Northwest Wales is undoubtedly fascinating, but by its very nature can be remote, dangerous and challenging. A significant proportion of the landscape is within private ownership and some of this on land where no public access is permitted.

“Before you set off to explore the slate landscape, ask yourself, am I allowed to access this site? Do I have the right gear? Do I know what the weather will be like? Do I have the knowledge and skills for the day? Go to AdventureSmart.uk to find out how to enjoy your visit safely.”
