Friendly Keystone is a well-run resort that offers fun aplenty for beginners, intermediates and snowboarders of all levels...
Keystone's main selling points are its multitude of great cruising pistes and fantastic terrain park.
The resort, which is often eclipsed by its sexier neighbours Vail, Breckenridge and Beaver Creek, also has a reputation as a great place to learn to ski or board - although this leads to complaints of too many beginners from those higher up the food chain.
Resort height: 2,830m
There are three mountains to choose from: Dercum Mountain, North Peak and The Outback.
And with lots of steeper slopes for experts thrown into the mix, this makes it ideal for mixed ability groups.
Visitors to Keystone also praise the fast lifts and excellent grooming facilities, as well as the night skiing that is available on 15 of the pisted slopes.
The A-51 terrain park, meanwhile, gets rave reviews and is consistently ranked among the best in the country by ski and snowboard magazines.
It too is open after dark and offers a dizzying range of jumps, tables, half-pipes, rails and jibs - as well as a superpipe for the brave.
Serious big mountain skiers, however, would do well to turn around and head to Vail or one of the resorts in Utah rather than planning a trip to Keystone, which is flat in comparison.
Keystone ski resort is in Colorado about 90 miles west of Denver airport...
The bad news for British visitors, however, is that most flights from the UK go via a US hub such as Washington or Boston.
Snowboarders - and skiers who like trying out their skills in the park - will love Keystone...
The resort is also really well set up for families, with lots of confidence-giving slopes for beginners and intermediates alike.
Cute, convenient and affordable, Keystone has some gorgeous restaurants, but fewer happening bars...
The young riders who come for Keystone's renowned terrain park can help to create a party vibe. In general, though, Keystone is a family resort with a fairly tame après-ski scene. Plus points include that the locals are friendly and that the resort is home to some delicious eateries, notably the Alpenglow Stube and the Ski Tip Lodge.
Keystone offers many of the same activities found in ski resorts - such as tobogganing and snow-shoeing. Other options for non-skiers include a visit to a relaxing spa and a browse around the resort shops, where you can buy gifts and jewellery as well as ski gear.
Cost of living 7/10
Keystone is a relatively affordable choice, particularly when compared to more luxurious neighbours such as Beaver Creek. You can also keep costs down by searching for ski pass, ski hire and activity packages.
There's still that long-haul flight to pay for, though.
Attractiveness of the resort 6/10
Keystone, like all the Colorado ski resorts, is purpose built. And here, the theme is very definitely traditional Alpine ski village, seen through American eyes. The result is cute - but could feel fake if you're used to the real thing.
