Y Garn

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
947 m (3106 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
The 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
Y Garn (3000ft+) lies N of the Pass of Llanberis in the Snowdonia National Park (Wales). To the SW it rises from Nant Peris in an almost continuous dull grassy slope; whereas on the NE side it rises with bold crags above Idwal Cottage and encloses a fine hanging valley containing a tarn (Llyn Clyd). Its short and steep NE ridge encloses Cwm Clyd (corrie) and provides the best ascent route from Idwal.

A second short ridge runs SE turning E to form the headwall of Cwm Clyd then terminates in crags, but it is the broad SSE slope of the mountain, rather than a ridge, which must be descended in order to continue past Llyn y Cwn and on to Glyder Fawr (3000ft+) .

A third ridge descends 0.5km NW to the 750m-contour col with Foel Goch (831m); and from that col there is a path which contours below both Foel Goch and Mynydd Perfedd (812m) right around the head of Cwm Dudodyn, leading after about 2.8km to Elidir Fawr (qv) with minimal extra ascent.

Hazards you may encounter on Y Garn include
 Steep slopes on or near ascent routes.
 Stony/rocky Slopes on or near ascent routes.
 
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 fantastic day out on a beautiful sunny day. I started at Idwal Cottage and followed the route set out here. The ascent from Llyn Idwal through the Devi's Kitchen to Llyn y Cwn is very steep with some scrambling. From there up to the summit of Y Garn is quite a slog on a fairly boring featureless slope but the view from the top is spectacular. The walk from there down onto the ridge and up to the ridge of Elidir Fawr is straightforward on a good path. Some scrambling is required to get yourself over a rocky crest on a narrow ridge which then widens out and leads to the small boulder field on the summit. The route down is long and punishing on the knees with some scree slopes to negotiate but nothing too difficult.
