A few extra kilometers walking at the start due to icy roads. Thanks to YHA Llanddeusant for letting us park up there. An easy trudge up the track to the small glacial lake Llyn y Fan Fach under blue skies.

Climbing the ridge up the northern face of the Carmarthen Fans behind the lake gives good views of as the Sandstone ridge sweeps eastwards toward our route and the peaks of Picws Du and Fan Brycheiniog (802.5 m/2,633 ft). Deeper wind-blown snow and decreasing visibility made the going somewhat sweaty.

An excellent day out and in contrast to nearby Pen y Fan that would have been packed with day-trippers, we saw nobody. Allow around five hours for the round trip (less if you park at the bottom of Llyn y Fan track) and go prepared for rapidly changing conditions (and a much longer walk out if you descend too far east). Know your weather forecast!
