From Rhiwlas, with AT and JT. Took the lane NE to Tynllidiart, then track around hill to a gate, then steep path up to the trig, not marked on map. Continued to traverse three possible HPs. Then descended to Pen y Bwlch Farm, taking the road around to Ffridd Uchaf, to avoid barbed wire. Then RoW to bwlch between hills, tackling Moel Rhiwen and then Parc Drysgol. Then descended back to Rhiwen via Maes-nieddygan back to Rhiwlas.
