Kevin Costner's Aspen Retreat is its own winter resort. The 160-acre ranch hosts three lodge-style houses that can accommodate up to 34 guests. You won't have to go far to look for entertainment. The compound includes sledding hills, an ice skating pond, two lakes for fishing, and its own Field of Dreams. Yes, the actor built a baseball field to commemorate his role as Ray Kinsella. For relaxing, there's also three hot tubs, outdoor terraces, and fire pits to take in the surrounding mountain views. But don't get too comfortable, the compound is only available for rent.
