A reminder of when the area was heavily worked, part of the old Slate Level.

Idwal Gorge is a dramatic, steep-sided ravine located above Llyn Idwal in Eryri (Snowdonia). Known for the Idwal Staircase, it offers a challenging "Grade 2" scramble through mossy, water-worn rock and hidden cascades. In winter, it is a premier destination for ice climbers. Carved by glacial meltwater, this rugged cleft provides a raw encounter with the powerful geological forces that sculpted the iconic Ogwen Valley landscape.

After the rest stop at Llyn Y Cwn we descend and pass the Devil's Kitchen (Twll Du) again. The descent is as strenuous as the climb. The path, as far as can be seen, is quite steep in places. Then it becomes a matter of paying attention, scrambling and searching for the next section of the path. This is not such an easy part of the route. You have to use your hands and feet to conquer the steepest parts.

Just a little slice of paradise. Was the only person there, I hadn't actually seen a person all day. So..... a bit of free swimming was required

This segment is straight out of Lord of the rings!!! Long steep rocky paths, high slate stack each side of you, old tiny abandoned dwellings dotted around, cracks in rocks with waterway paths to hidden safe havens from orcs. This place is just something else!!!!

This gloriously tranquil valley takes you deep into the Carneddau, where a scramble up the Llech Ddu Spur or rock climbs on the Ysgolion Duon (Black Ladders) awaits. The intimidating Llech Ddu buttress looks immense towards the head of the valley, in contrast to the peacefully meandering Afon Llafar. If you're lucky, you might meet a few of the Carneddau's semi-wild ponies.

The Devil’s Kitchen is the name given to the dark, black crack which splits the rock of Clogwyn y Geifr (Cliff of the Goat) between Y Garn and Glyder Fawr. The Welsh name for Devil’s Kitchen is Twll Du, meaning ‘black hole’. Twll Du is known as the Devil’s Kitchen because of the plume of steam that is often seen rising from the crack resembling a chimney. It’s said when steam can be seen rising from the chimney, the Devil was cooking.
