Parking and Approach

'Easiest', as in least strenuous, approach from Gerlan (SH634665), above Bethesda. A narrow surfaced road leads to the uppermost bridge over Afon Llafar to Ty-slatters and the water treatment works, here is the start of the path. However, getting to this point involves some tricky navigation.On entering Bethesda from the Ogwen Valley take the first turning on the right (SH626660); this is Braichmelyn. Continue along the road and over a bridge, then go steeply leftwards to a junction. Turn sharply right and continue along a narrow road to aPost Office and chapel; park here. Walk along the farmland to where the road drops down to a small bridge over Afon Caseg. It then rises back up to reach a fork. Take the right hand path to reach the bridge over Afon Llafar. Cross this and then bear left to reach the water treatment works. A stile immediately right of the cates takes one around the water treatment works to a ruined farm and an ancient trackway leading over an ancient bridge to a stile. Marshy anclosures give access to open moorland and the mouth of the Cwm Llafar valley where a better track is attained. This follows the SW bank of the Afon Llafar to a point Beyond Llech Dhu, where it peters out alltogether. An ill-defined path then leads into the upper cwm. Boulder screes and water-logged ground provide options leading to the final steep incline.
