This walk, exploring the historic Nannau estate and the lovely countryside around Llanfachreth, is packed full of interest. The route follows quiet paths and country lanes through green meadows and woodland and past various sites of historic interest. Along the way it also provides some fabulous views over Cadair Idris, the Aran range and the Mawddach Estuary. We start by heading a short way down the road, soon turning off to walk past the remains of old fish-ponds and though the Nannau Deer Park. We continue towards Llanfachreth, passing Pwll-y-gele (Pool of the Leeches) which has a fascinating history - it is one of several pools in Wales where leeches were bred for medical use! Next we head downhill to visit the remains of an old copper mine. From here we climb up again to join the well-known Precipice Walk which we follow back to the start.
