I camped at ribbon lake last summer, and really enjoyed it. Its a nice area, between the spray lakes area and the kananaskis valley. The area has three campsites (ribbon lake, ribbon falls, and lillian lake) and three three hiking routes in (Buller pass from the spray lakes side, ribbon falls and galatea trail on the kananaskis valley side). We hiked in and out via Buller pass, but with two cars you can easily come in via one route, camp at one of the sites, and head out a different way. Overall, its a great location, the campsites were really nice, tons of great views, and the hiking routes aren't terribly strenuous.

I also made a trip to turbine canyon with a group of people. I highly recommend that site as well, although it was a much tougher hike, and the campsite wasn't nearly as nice.
