    Hiking

    At 644 metres, Twyn Mwyalchod is another local and pretty accessible trig point. It can either be a reasonable short up-and-down hike, though a steep one, or you can make it a long day by adding it on at the end of the Pen y Fan Horseshoe. There are great views up the Neuadd valley to be had from here.
