Llyn y Fan Fach is a beautiful lake situated below the Black Mountain escarpment. You can reach the lake within short walking distance from the Llyn y Fan Fach car park but please note it's small and gets quite busy. Folklore tells the story of 'the Lady of the Lake'. It's a great place to explore the ridge of the Carmarthen Fans surrounding the lake.

Old Trout Farm on the Afon Sawdde

Highlight • Structure

The route from here up and around Llyn Y Fan Fawr and Back must be a strong contender as one of the Wales’s most scenic walks. This is just the old trout farm on the Afon Sawdde on the start of your walk really. When I say old, it is old in structure but still being used to breed fish and is a nice half way marker on the way to Llyn Y Fan Fach itself. The nicest thing about this part of the walk is that there are abundant photo opportunities as you have the river, mini waterfalls and the main escarpment of Fan Fach in front of you,
