Preview from Exceptional Stays's listingHomes whose own manager listing says ski-in/ski-out for that home, in those words. Shuttles and walks to the gondola do not count.
The standard is the manager's own listing page using the phrase ski-in/ski-out for that specific home. StayClubs holds the club until a manager or ski-market operator takes it on.

Ski-in/ski-out is the most stretched phrase in mountain lodging. Shuttle stops, gondola walks and near-the-lifts all get sold under it. This club keeps only homes where the manager's own listing page says ski-in/ski-out for that home, and quotes the sentence so you can judge the wording yourself.
Twelve homes from nine managers across Telluride, Steamboat, Park City, Breckenridge, Jackson Hole, Big Sky, Beaver Creek and Whistler. Each links to the manager; you book with them.
