Big Sky? Super stoked. Enormous mountain now that the merger with Moonlight has happened - and with a huge variety of terrain: trees, chutes and steeps, groomers. Enough to keep a group of 7 snowboarders with the full range of ability happy. What sets the place apart is the beauty of the terrain, and the real warm welcome from the locals. Great range of accommodation. Yup, buy your groceries in Bozeman first, but don't sweat it. It's really worth the trek. Our week here included some powder days and a few super cold days, so you get nose (freeze? editor) but it keeps the snow in great shape. And we didn't mind coming down to one of the base areas for a feed at lunch. We also had a great week in Jackson just before but I'd still rate this mountain above many of its North American competitors; friendliness, good infrastructure, complete lack of crowds and awesome terrain.
