Pennard Golf Club in South Wales

Little has changed at Pennard Golf Club in Wales since it was established in the 19th century. It's one of Wales' most shocking golf courses and a favorite of the game's purists. Architect Tom Doak puts it among his five best undiscovered links courses in the British Isles.

It's rugged and quirky with a fairway that's barely defined in most spots, and free-range animals have been known to make their way onto the course from time to time.

The par-5 16th hole is an incredibly beautiful sight, overlooking the rocky sea well below. It's a big reason why Pennard has been dubbed the "links in the sky".
