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.
