The cache is small container with a log book only, so bring a pen, hidden by a small rock.
Best approached from Cwm Gwdi, its an uphill slog but the views get better the higher you climb. Path is clearly defined, just keep going up and up. Continue past GZ to reach the summit of Pen Y Fan.
Only attempt in good weather if your not competent with your navigation skills,as there is a drop either side of the ridge.
