I am not a rock climber but wanted to hike in to see one of the Kelowna Crags for fun. The crag I heard of is in Cedar Mountain Regional Park. Kelowna actually has 4 main crags, and the Boulderfields are the largest Kelowna crag. I found the large crag in Cedar Park be a cool place to see and the fact that you can hike up a steep trail on the Northeast end of the crag to enjoy awesome views of the Okanagan Lake, makes the short hike worth your while. The custom made rock chairs at the top of the crag looks inviting! It only takes 10 minutes or so to hike to the crag from the Cedar Mountain Regional Park Trail Head. ( Trail Head Map)

Here is a review from a Rock Climbing in British Columbia website. This outdated writeup pulled from http://www.geocities.com/climbingbc/multipitch.htm is just referring to one climb, though Cheops, that has maybe seen half a dozen climbers on it in the past 10 years.
