The St Mellon’s Hotel is a stunning country house hotel situated midway between Cardiff and Newport. Set amongst acres of parkland around the St Mellon’s Golf course, the hotel offers a peaceful retreat, a venue ideal for overnight stays, wedding receptions and conferences.

Our 20 bedrooms are in the process of being refurbished, the majority of which will be finished early springtime. The hotel offers a peaceful retreat for residents at the Panacea Health Club, which is complimentary, along with excellent conference, events and dining facilities.
