Ski in / ski out properties range from multi-million dollar homes to small studio condos. Most are found in Breckenridge but you'll also find them at Keystone and Copper Mountain. These condos offer convenience that's hard to top. Strap on your skis or boards outside your door and ski back to your door at the end of the day. It's what a Summit County condo is all about. In the summer, the ski areas turn into hiking and biking runs, Breckenridge has the Adventure Park with alpine slides and other rides. While ski in / ski out properties are primarily for winter fun, they aren't just for winter any more.
