Montaine
By Jessica Carcoana · Updated September 2026
Montaine is Castle Rock's newest master plan, underway since 2020 with Toll Brothers building its Overlook and Estate collections from 2,567 to 4,314 square feet alongside Wonderland Homes product on 6,000 to 10,000 square foot lots. A resort-style clubhouse anchors the amenity package with a pool, water play area, and fitness center, set within 548 acres of open space threaded by 13 miles of hiking and biking trail. The community looks west to the Rockies and east across the plains from its ridgeline lots. Crystal Valley Parkway connects to I-25 in about five minutes, with Plum Creek Parkway as an alternate route.
