The American architect Denis Griffiths designed the 7,162-yard mountainside course at Chatrium Golf Resort Soi Dao Chanthaburi (formerly Soi Dao Highland Golf Resort).
Griffiths holds the distinction of being the only American architect to design a golf course in St Andrews. In 2015, local Thai architect Pirapon Namatra of Golf East redesigned a number of holes and altered the routing.
It has been more than ten years since I played this atypical Thailand golf course, off the Cambodian border, about 3 hours drive from Pattaya. It's hard to recall details, but it was quite a spectacle. The course is routed through a spectacular mountain and forest landscape, which enables a fair degree of challenge. The other recollection I have is that the design was quite natural and quite unlike some of the overdone courses you come across in Thailand.
The only question here is its isolation - but if you are looking for a quick and quiet golf break in Thailand, this could well be the place.
