Living at Regency at Montaine

Welcome to Colorado’s most prized threshold, and Castle Rock’s new 55+ active-adult master-planned resort-style community.

Discover Montaine
Amenity Center 3D Walkthrough 

This unique land, its legacy, and the cherished lifestyle of living at the front door to the great plains of Colorado to the east, and the majestic Rocky Mountains to the west. From atop Mount Montaine – the highest point in our community, and the highest vantage point throughout Castle Rock – you can see yourself living here, growing here, and loving every moment here.

Life in Montaine is meant to be lived. Spend your free days traversing varying topography. Cherish your nights gazing at more stars than you could ever imagine. Get to know the towering trees that welcome you home. Take a deep breath where they open to remarkable views of Castle Rock’s famed buttes. Escape the daily hustle and bustle, even before pulling into your driveway.
