Carnedd Llewelyn

English/Welsh
Quick Facts
This is the height of the mountain above sea level. However, on the climb, it is the ascent that matters, i.e. the sum of all the uphill parts of the route.
Altitude
1064 m (3490 ft)

This is the standard notation used on Ordnance Survey Landranger maps.

Each reference consists of two letters identifying a 100,000 metre square block then three digits defining the Easting and finally the three digits defining the Northing with reference to the South West corner of the block.

NN166712 is the grid reference for the summit of Ben Nevis. Where you are given the map number ( For Ben Nevis = 41) it is acceptable to omit the two initial letters e.g. 166712. (Instructions on how to read the references are given on the OS maps).

Mountain names are usually in Gaelic, the native language of the Scottish Highlands, or have been derived from the old Scots and Norse languages. We give the most commonly accepted meaning, but accept that some of these are disputed.
Meaning
Llywelyn's Cairn
 

The UK is covered by 204 Ordnance Survey Landranger 1:50,000 scale maps. Maps numbered 1 to 86 cover Scotland but for the highest mountains (Munros) only 23 maps are required. The name given roughly describes the area covered by the map.

A description of the characteristics of the mountain including any hazards of which you should be aware.

  Description
Carnedd Llewelyn (3000ft+) is a cruciform mountain with 4 distinct ridges NNE, E, S and NW, and lies at the hub of an extensive group of hills in the Snowdonia National Park (Wales). It has a rounded stony summit which lies close to crags falling steeply on its NE side to a small tarn, Ffynnon Llyffant.

To the S a broad ridge turning SW drops to Bwlch Cyfryw-drum (933m), the col with Carnedd Dafydd (3000ft+) . The NW ridge, with crags on its NE side, extends 1.5km to the shapely pyramid of Yr Elen (962m) which has crags especially N and W. The E ridge, turning SSE, has crags on its N then E sides, and forms an arête at Bwlch Eryl Farchog before rising to Pen yr Helgi Ddu (833m, a distance of 2km), thence continuing S to the valley bottom near Helyg. The E ridge from Pen yr Helgi Ddu drops to Bwlch y Tri Marchog, the col with Pen Llithrig y Wrach (qv.). Finally a broad NNE ridge, initially with crags to E, runs NNE to a plateau area before rising slightly to the broad top of Foel Grach (976m) then on to the 884m col with Garnedd Uchaf, a subsidiary top of Foel-fras (3000ft+) .

The ascent of Carnedd Llewelyn is conveniently coupled with nearby Carnedd Dafydd for a leisurely day outing. It is possible for strong and fit walkers to combine the Carneddau with Pen Llithrig y Wrach (2500ft+) or Foel-fras in a full and strenuous day, bagging 3 mountains without detour.

Hazards you may encounter on Carnedd Llewelyn include
 Crags near summit.
 
General Considerations
 Temperature decreases by 1degree C for every 100m of ascent.
 Wind usually increases with altitude.
 Visibility can change markedly with cloud level.
 River/Stream levels can increase markedly in one day.
A special thank you to David S Brown for his work on this and all of the England/Wales information.
