Well said.
It totally depends on what you are looking for. Camping, day-trip, hike-in, big lake or tiny.
Don't expect to catch whales, but there is plenty of fun to be had in Kelowna area. I'm from Kamloops, but always go to Kelowna when in Canada to spend time with friends and enjoy a bit of fast fishing after the rather zen-like trophy hunting that I find myself doing in my home town.
I always suggest one of my favourites Oyama Lake as a great camping lake that is quite scenic (something like 17 islands!). If you can find the right spot it has good fishing with some nice sized fishes as well. All the usual flies work well but beware the submerged logs, you will lose some flies, tippet, and leader material.
Also has a resort if you want to rent a cabin.
Cheers,
