| 2/7 Dewey day. From Blaengwynfi following the zig zag forest road to the mast, then further forest roads to Mynydd Ynyscrrwg, then around the head of Cwm Gwynfi using easy road past turbines before branching off to the right to the Mynydd Blaengwynfi trig just off the track on the right. Retracing the route back to the main forest road and south east to SS 918 962 from where the edge of the forest is followed to the broken trig of Twyn Crugyrafan. A slight descent to cross the A4107 at the summit then up access road to the masts at Werfa, behind which the summit trig hides. Then following small tracks over the grassy top of Werfa west down to the col, where the new wind farm road is joined up the hill before branching off to the trig at the summit of Mynydd Caerau. Finally back to the col and then easy traverse of the grassy pasture heading north along the bridleway until a really awkward and very steep descent without track has to be negotiated down into Abergwynfi, and then throug | silveracorn_alan | 26/07/2020 |

| Started in Upton Street, Blaegwynfi and followed track up into forest. Followed track to SS 89982 96953 and turned left. Again followed track. Quite a mess in places with bike tracks cutting the track up. Turned right at SS 89965 97370 and followed track to Mynydd Blaengwynfi. Reversed track for a short distance and then followed a series of paths and tracks to Twyn Crugyrafan. Descended to road and then up to top of Werfa. Crossed moor and climbed up to top of Mynydd Caerau. Steep at start of climb up. Walked across moors back to Blaengwynfi. Good walk. Mainly on tracks and paths but badly cut up in places by the boys on bikes. | MikeM | 05/05/2016 |

| From Blaengwynfi up path to forest track (note the upper one isn’t obvious from top of path). Then on over tracks and paths to trig point (keep your eyes peeled – screened by trees). Round forestry tracks past a wind turbine base and on up past old water tank to summit. Made mistake of trying to drop from mast to village on old track (don’t). Came down to west on tracks in the end. | SS | 15/03/2015 |
