Devil's Kitchen (Twll Du)

Highlight • Gorge

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.

Don't go another way back to the parking place! It's worth it. At first the wonderful view to the valley and than this canyon at the end.

Nantlle Valley

Highlight • Gorge

Bounded by the sinuous switchbacks of the Nantlle Ridge and the 'Elephant Mountain' of Mynydd Mawr, the Nantlle Valley is one of Snowdonia's quietest and most scenic beauty spots.

Characterised by a number of small former slate mining villages and the remains of the industry, it is thought that around 85% of its inhabitants still speak Welsh as their first language.

Cwm Pen-llafar

Highlight • Gorge

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.

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.
