I also enjoyed Koolau with the jungle feel and changes in elevation and forced carries.
I have so many things about Koolau. Is it really as tough as advertised?
Tommy - first of all thank you so much for all the effort you put into this thread. I have spent a lot of time playing golf in Hawaii and have played most of the courses you mentioned, so I particularly enjoyed your thoughts on them...
Koolau is a very difficult target golf course in the sense that if you miss the target, your ball is in dense jungle and not likely to ever be found again. If you keep the ball on the short grass its playable, the problem is the magnitude of the penalty for bad shots. The back tee has a course rating of 78.2 which basically tells us a scratch golfer from back there should shoot about 78. I guess its just hard to hit the target when you are playing a long course like that. But if you play a reasonable set of tees for your game (that may be a combo of various tees) I think its a very enjoyable outdoor experience as the scenery is spectacular.
Note it is on the rainy side of the island - the first time i tried to play it I got rained out and had to come back the next day (and it rained again during the round) - however the misty rains against the massive towering pali cliffs in the distance plus the jungle and ocean views in the distance on a few of the holes on the back nine make for what i found to be a fun day (even though I ran up the scorecard on the holes where i went astray). Given the frequent damp conditions, the yardage plays even longer and the course can get oversaturated.
I would put in in the category of fun to play on a vacation as an outdoor experience, but would be a tough place to play everyday. I would love to get back there and try it again. If you do head over there do not miss the Nuuanu Pali Lookout (15 minute drive from Koolau) which overlooks Koolau and its neighboring courses and the whole east side of the islands - spectacular!
I know you mentioned you haven't been to Oahu, but there is a lot of other very enjoyable courses on Oahu including Waialae (really looking forward to returning to see Doak's restoration work), Oahu CC and Mid Pacific on the private side and in no particular order the public side: Royal Kunia, Koolau, Royal Hawaiian (fka Luana Hills), Ko Olina, Kapolei, Ewa Beach, Turtle Bay and one of my all time favorite sleepers the MUST play Kahuku...although it just got a big article in Golf...if you go to Kahuku do not miss the Giovanni Shrimp truck! I also know there are some good military tracks on Oahu including Kaneohe Klipper, but I haven't played any of them...
Perhaps my favorite spot in all of Oahu is the Outrigger Canoe Club - sitting in their bar or outside there at sunset is just magical - no golf course but one of the all time coolest beach clubs if you get the chance to visit.
I know many here on the board wouldn't want to play most of these courses, and I respect their opinion, but for me playing golf in Hawaii almost anywhere is a lot of fun - I just love being outside there early in the morning on the golf course.
