I'll second 16 at Port Royal and throw in...
Approach to the 11th at Port Royal
From the tee on the 13th at Mahogany Run on St. Thomas, USVI (in spite of the bad golf)
Standing on the 3rd green at Buccaneer GC on St. John USVI (in spite of the bad golf)
Approach on 16 at Cabo del Sol Ocean
From the tee on 17 at Cabo del Sol Ocean
From the tee on 7 at Cabo del Sol Ocean
From the tee on 8 at Cabo del Sol Desert
Actually the most spectaclar view I have ever seen on a golf course was at Port Royal. Standing on the 8th tee, a downhill par 3 with the ocean just behind the green. Two massive water spouts dancing about perhpas a half mile off shore just behind the green on a sunny Bermuda day. Sorry, I am not a camera kinda guy.
