Quite a tricky path. Easier up than down I reckon. I did it with a wonky arm so don’t worry too much.

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,

Ahhhh Llyn Y Fan Fawr, this glaciated lake is about the nicest place you can be on a hot summers day or even a cold winter's morning. It has been central to my working life in the hills for nearly forty years. It is just so perfectly locacted and makes for a good check point with groups, a rest spot, a camping spot and a perfect wild swimming spot on a hot day. Don't listen to the naysayers, this has been an iconic wild swimming spot for eons. Apart from that it will be a tad cold, it is just about one of the best swim spots in the Brecon Beacons.
