Choosing to live in the high desert of the Grand Valley in Colorado offers a unique and appealing lifestyle for various reasons.

One compelling reason to live in the high desert is the climate. The Grand Valley experiences over 300 days of sunshine annually, coupled with low humidity. This results in a dry climate, making the region ideal for those who appreciate brilliant clear blue skies and a distinct four-season climate. The dry air also contributes to the stunning landscapes, with the Book Cliffs, Colorado National Monument, and the Grand Mesa providing breathtaking views.
