Moelwyn Mawr

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
770 m (2526 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.

  Description
Moelwyn Mawr (2500ft+) and its partner Moelwyn Bach (710m) are relatively isolated peaks lying WSW of the slate-mining town of Blaenau Ffestiniog, in the Snowdonia National Park (Wales), and prominently seen to the E from the Beddgelert-Porthmadog road. Their N and E aspects bear ample testimony to their slate-mining history. Moelwyn Mawr has short N, E and S ridges, and a long W ridge running to the little hamlet of Croesor. The S ridge passes over the narrow craggy edge of Craigysgafn (689m), thence to the col with Moelwyn Bach, which itself has a long gentle W ridge.

The two are most conveniently climbed in a circular walk from Croesor using the two W ridges, thereby avoiding the old slate mine workings and spoil-heaps of the lower slopes.

Hazards you may encounter on Moelwyn Mawr include
 Stony/rocky Slopes on or near ascent routes.
 Crags on or near ascent routes.
 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.
