Going to southwest England in June for a wedding. Will have 3 or 4 days to explore before the wedding. Anybody been to Wales? Was think about going to the southern coast of Wales then up to Snowdonia.

Thoughts?

I've been through Wales once when doing a study abroad trip with NC State right before I graduated. It is definitely unique and worth going to if you have the chance. Powis Castle isn't exactly in southern Wales but was very impressive. The city of Cardiff was a stop as well that's worth exploring.
