Built in 1280, this castle has a fascinating life story. It is the second largest castle and grounds in UK, slightly smaller than Windsor castle. The water defenses are now home to plenty of birds and the grounds offer fantastic views of this stunning castle

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.
