This is a spectacularly beautiful golf course, carved out of the tropical rainforest nestled against the Ko‘olau mountain range. It’s also spectacularly difficult—narrow and winding, with extreme changes in elevation. Legend has it that when Koolau Golf Club first opened, it was so difficult that it was given a slope rating of 162…where the maximum slope rating is 155. The official rating has dropped to a still formidable 152 from the back tees. The windward side’s wet conditions don’t make it any easier (and now you know why this side is so green and lush). But when things get frustrating, just take a breath, look up at the mountains, and marvel at the beauty that surrounds you. Facilities include a pro shop, driving range, putting and chipping greens, and restaurant.
