Route

The walk climbs a track all the way to Llyn Fan Fach (a lake). After time resting at the lake and learning the about the legend of the Lady of the Lake we climb to to top of the ridge and get impressive views looking down on the lake. We then follow the ridge of the Carmarthen Fan to its summit Picws Du which is the highest point in Carmarthenshire. The route descends a bit at Bwlch Blaen-Twrch before climbing again to the peak of Fan Foel which forms the county boundary of Carmarthenshire and Brecknockshire. We then follow the ridge around to reach the highest point on the Black Mountain: Fan Brycheiniog which is an ancient name for Brecknockshire. Our route then descends to a second, bigger lake, Llyn y Fan Fawr, which is also the source of the River Tawe, the river that flows through the City of Swansea. We then walk around the impressive peak of Fan Foel at the lower level to reach the glacial moraines near Bwlch Blaen-Twrch. From here we follow the stream back to the car park.
