Have only been here on skis, but enjoyed the skiing here. I found it to be challenging on tele skis, but would be the classic blue level run on Alpine skis. Would like to check this place out during the off-season.
Big Sky is expensive, but boasts some quality ski runs. The runs are routinely groomed daily and wide open -- a lot of skiers can be accommodated. Moonlight Basis, now a part of the Big Sky conglomerate, is even better for intermediate folks.
