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.
