Pen y Fan


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.
886 m (2906 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).

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

Pen y Fan (2500ft+) is the highest of the Brecon Beacons (Wales). It is the central top of a group of 3, the neighbours being Corn Du (873m) 600m to the WSW, and Cribyn (795m) 1.3km to the E.

These 3 tops are of similar appearance, having flattened summits and N-facing cliffs of subtly shaded horizontal stratified sandstone. Ridges with tracks extend NNE from Pen y Fan (Cefn Cwm Llwch) and Cribyn (Bryn Teg) making possible a circular walk over these 2 from the minor roads to the N; and a ridge NW from Corn Du permits a similar circular walk over Corn Du and Pen y Fan.

The main ridge from Corn Du runs SW turning SE with crags to the E overlooking Gwaun Taf, the head of the Taf-Fechan river valley which runs S to Merthyr Tydfil. The main ridge from Cribyn runs SE over a col at 599m where a vehicular track crosses the ridge. The ridge continues E to Fan y Big (710m) then curves round Cwm Oergwm to Waun Rydd (2500ft+) .

It is thus possible starting from the Taf-Fechan forest area and using the vehicular track to the 599m col, to traverse the 3 tops of the Pen y Fan group and circuit Gwaun Taf. In a longer outing from the same start a second 2500+ mountain (Waun Rydd) can be included.

Hazards you may encounter on Pen y Fan include
 Crags on or near ascent routes.
 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.
