Tucked away in a dreamy, isolated location in the upper Swansea Valley, Craig-y-nos Country Park is a gorgouous 40-acre park that was once owned by Adelina Patti. Now it is a Victorian garden set in woodlands, surrounded by meadows and ponds, dissected by the River Tawe. It is in a gorgeous location, and there is a great cafe there to boot.

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.
