Ewa Beach is the king of Oahu, Hawaii golf courses with a total of seven.  One of them is Coral Creek Golf Course located just west of the intersection of Kapolei Parkway and Geiger Road.  This course is a par 72 and plays around 6,700 or so yards from the back tees.  It is not my favorite course on the island but it is decent.  I wouldnt rush out to play this course if I was visiting Oahu but if you can get a good discount, it would be worth your money.

Awesome views from Koolau Golf Course.  This video does no justice for the real beauty of this place.  Supposedly, this is one of the toughest courses in the nation.
