Hyde Mountain expanded my vocabulary in not so nice words!
I don't know what is considered the Okanagan Region in B.C. But, I thought I'd add a few more from the area (or somewhat close).
Kokanee Springs:
Crawford bay, B.C. What an excellent course. This is probably, to date, tied for the best course I have played. The condition of the course is impeccable, the views incredible, and the enjoyment level through the roof. It's also my favourite course that I've ever played... very close is the next one listed.
Golden Golf Club
In Golden, British Columbia. An absolute dream. Conditions are incredible, each hole is like it's own entity. Rushing waters, picturesque views every way you turn, and it seems nearly every green is set into a surrounding of large coniferous trees. If you are ever in Golden, you've got to stop. It's worth the stop if you are passing through.
Bootleg Gap
In Kimberly, B.C. Quite a drive from the Kelowna region. But a nice track. I played it when it was very new. Lots of cool holes, but was more open than most course I've played in the mountain region. I'd love to go back and play it again as it has matured a couple of years.
Shuswap Lake Estates
This is right in the region, Salmon Arm, B.C. A nice track, but like Bootleg Gap very open for the mountains. But it's set right in the valley, not up the mountain side a bit like with Golden, or Hyde Mountain *shudder*. If you are staying for a while in the area, it's nice to try. 18 is a load of fun. But if you are passing through and only have a couple of rounds, I'd venture to other courses. Hyde Mountain is just down the highway... but I wouldn't suggest that one over some of the others mentioned either.
Revelstoke Golf Club
Revelstoke, B.C. Set on the Columbia River it's just down the highway a bit more from Salmon Arm. It's not the most spectacular course you'll ever play, but it's pretty good. Hole 6 is amazing as you walk up to the green which is set right on a bend in the Columbia River. It's spectacular. My favourite reason for going to this course by far. That and Hole 5, which is my nemesis, and I can't par that hole for the life of me... but it isn't that hard! A lot of holes are very tight, with a great amount of large coniferous trees surrounding every hole minus the last four or so. It is not abnormal to hear lots of balls hitting trees, because even the "easy" shots out of the trees are tight sometimes. I'd rate it like Shuswap. If you are around for a while, take it in. If not, you may want to hit others.
As you can tell, I'm not a fan of Hyde Mountain. I'd play it again for the sole reason I want to do better than I did. But it is one heckuva gimmick course. Every hole is up and down, blind tee shots all over creation, and if it's not a blind tee shot, it's quite possible they'll get you back with a blind approach shot. It was a lot more at the time then the others we played, and we got a deal with 12 of us. It's a post card a hole, but jeez I found it almost unfair at times. But like I said, I'd play it again because I have a drive and desire to show that course it won't get the best of me again!
