The Alta Ski Area in Utah is considered to have some of the USA's best snow, so if you're serious about your Winter sports, then you'll be impressed by the cloud-like powder.
It's just for skiers as boarders are banned (one of just three areas in the US that outright bans snowboarders) and is all about the snow, the history, and the lodges — no fancy nightclubs or boutiques here.
You can fly to Salt Lake City from the UK in around 13 hours (usually with at least one connection), then it's a 45-minute transfer. Utah is seven hours behind the UK.
