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

1044 m (3425 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).

Routes

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.

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

Description

Carnedd Dafydd (3000ft+) , one of the more northern peaks in the Snowdonia National Park (Wales), lies SW of its sister peak Carnedd Llewelyn (3000ft+) and NE of Snowdon. Its NNE slopes are craggy and fall precipitously into Cwm Glas, the upper reaches of the Afon Llafar valley; whereas its SSE and WNW slopes are grassy and stony.

Carnedd Dafydd has 3 symmetrically-placed ridges. The E ridge turns NE to Bwlch Cyfryw-drum, the col with Carnedd Llewelyn. The NNW ridge walls in the southern side of the Llafar valley. The SW ridge runs 1.5km to the subsidiary top Pen yr Ole Wen then descends steeply to the W end of Llyn Ogwen. An E ridge from Pen yr Ole Wen provides a gentler descent route S of Ffynnon Lloer thence down the S slopes to Llyn Ogwen. It is usual to combine the traverse of both Carneddau into a single round walk from the A5 road E of Llyn Ogwen.

Hazards you may encounter on Carnedd Dafydd 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.
