Aka "Cloggy". Translated probably means "The Black Cliff of the Black Hollow".

This daunting crag is generally accepted as being the best crag in North Wales, with nothing really below 5.8. It's split into many buttresses, with most of the climbing on the East and West of those buttresses. The East (including the Pinnacle) holds many steep face and crack climbs and the West contains a sequence of leaning and overlapping slabs.

Certainly a traditional Welsh mountain crag of a higher level of difficulty and it should be at or near the top of every visiting climber's list of places to climb - as long as the weather is good and the rock is dry.

Getting There 

From the A4086 heading towards Llanberis turn left at the Snowdon Mountain Railway and follow the winding narrow road to the Snowdon trailhead appears on the left, park in a pullout on the left just past this trailhead.

Hike up the Snowdon trail for about 2 miles, passing Halfway House on the way, before the main trail heads steeply up take a right fork, this climber's trail heads slightly up and around the Cwm to the bottom of Cloggy. About an hour for the fit.

The hourglass shaped white slab is quite distinctive on the approach. This is one of the great Welsh slab climbs, if not the greatest, it's a big atmospheric mountain route, especially on a dank and cloudy day. The slabs are more steep thin edging than smearing.1. 5.10a - From the top of the shattered pinnacle traverse go down and left along the lip of the overhang, passing a shallow groove (used to be a pin here, not sure anymore) to another groove, up this to a large flake and belay.2. 5.7 - ...[more]   Browse More Classics in International

A [Welsh] pedant comments: "Clogwyn Du'r Arddu" is the correct version. "Du" simply means black in Welsh. Lots of emphasis on black!
