Y Lliwedd


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.
898 m (2946 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.
Coloured peak or the Viewpoint

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.

Y Llewedd (2500ft+) is a splendid peak in its own right, narrowly qualifing as a separate mountain with 505 feet of ascent above the Bwlch Ciliau col with its lofty neighbour Yr Wyddfa (3000ft+) in the Snowdonia National Park (Wales).

Y Llewedd has twin rocky summits, the W Peak (898m) being 5m higher than the E Peak (893m); and both are poised sensationally at the edge of the N face, a near-vertical cliff of rock which is a favourite with rock-climbers. The S slopes are steep with scree and rocky outcrops.

Y Llewedd forms a single ridge which from Bwlch Ciliau rises steeply SE (with scrambling) to the peaks then E to Llewedd Bach (818m), thence NE to an unnamed top at 694m and finally E down to the Glaslyn valley. The traverse of its fine summit crest is an integral part of the ‘Snowdon Horseshoe’ walk.

Hazards you may encounter on Y Lliwedd include
 Stony/rocky Slopes on or near ascent routes.
 Crags near summit.
 Narrow Ridges, with exposure.
 Scrambling (minor), easy hand and footholds.
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.
