The views down onto Llyn Y Fawr from here is pretty spectacular. This is one of the nicest places in the Brecon Beacons to walk along. Once you have put in the effort to get here, the ridge has a good footpath, there's a nice walled shelter and the views down towards the lake is pretty awesome on a good day.

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.
