I've been lucky enough to have played Cypress Point on many occasions, with 1983 being the first. I have never played another course like it with so many variations. To play the inland holes that are beautifully sculpted, then play the holes throughout the sand dunes, with the remaining holes playing toward and on the ocean, is so unique.
It is truly my favorite place to play golf and part of that is because of the setting and surrounding areas. It is such a peaceful place and I've never had that feeling any other place I've traveled to. I've had people ask me if it is the best 18 holes of golf I've ever played and I would have to say no. There are some holes out there that I think are good, but not great. It's the overall experience that elevates everything, but I agree with some other posters that holes #3, #4, #6, and #11 are good, but nothing special.
On the other hand, holes like #7, #8, #9, and of course holes #13 - #17 are all world holes.
When I think of the best 18 holes I've ever played, Sand Hills is the overwhelming favorite for me. JMO
