The original owner had first choice of any lot at Keystone Ranch and chose this location. It's stunning, private, and offers some of the greatest views you'll find anywhere. This classic Keystone design has been thoughtfully reimagined and completely updated to the very highest standards. True Colorado views from every room, every window. Walk to the clubhouse, Ranch restaurant, and exclusive pool in the summer. Excellent in every way.
