Nakiska is a decent ski area if you are a beginner or intermediate skier. Little bit less expensive than Sunshine/Louise so probably a better value if you aren't quite skilled enough to take full advantage of those larger resorts.
There are, however, a couple things about Nakiska which sour my opinion of it:
First, if you are going midweek (as I did) you can expect the single major black diamond off the Silver chairlift to be closed due to racing team training. Unfortunately, that particular run is the nicest black diamond, in terms of snow coverage, on the entire mountain. Probably the best candidate for a lengthy mogul run, but again, due to racing team training that run is groomed. This wouldn't be so much an issue if the rest of Nakiska's expert terrain wasn't quite so... sketchy. By "sketchy" I mean that the black diamond runs off the Gold chair have fairly thin snow coverage. Much rocks and branches. Maybe this improves later in the season, I don't know. The Glade area (which closes at 3:15pm) is alright if you like skiing amongst lots of trees. I don't. The some of the black runs off Gold chair are also groomed.
Second, and this may be a minor quibble, is the sideways slant present in most of the runs towards the right hand side of the mountain. Right hand side meaning the right side of the trail map. Most of these are slightly canted so that you will be spending a lot of time with your weight on one foot in order to keep yourself headed down the center of the run. I found this uncomfortable to the point of avoiding those runs (specifically #29, #44, and #4) for the remainder of the day.
For experts: The Glades are okay in good snow conditions if you like skiing in trees. Several black runs are groomed. Double blacks in proximity to Silver chair were very sketchy. Expect some damage to the bases of your skis if you venture on them. Bring rentals, maybe?
