Westcliffe and Silver Cliff hold Colorado's first International Dark Sky Community designation, and one of the highest elevation ones in the world. Here is what that title actually protects, and what it means for anyone buying property here.
Step outside on a clear night in Westcliffe and you will understand the designation before anyone explains it to you. The Milky Way is not a faint suggestion overhead, it is a wide, bright band stretching across a sky with almost nothing to compete with it. That is not an accident. It is the result of a community that decided, deliberately, to protect something most towns lose without ever noticing.
In 2015, Westcliffe and Silver Cliff became the first International Dark Sky Community in Colorado and the ninth in the world, a designation held by DarkSky International. The two towns sit between the Wet Mountains and the Sangre de Cristos, high enough and remote enough that the glow from larger cities never reaches the horizon, and at more than eight thousand feet in elevation, this is also the highest elevation Dark Sky Community anywhere. The Smokey Jack Observatory, built the same year, grew out of decades of local effort by residents who saw what was worth preserving here well before most places were paying attention.
Earning that designation was not simply a matter of having dark land nearby. It meant the towns adopted real lighting standards, replacing streetlights and public building fixtures with versions that are shielded and aimed downward rather than out and up, using a warmer, softer light rather than the harsh white glow so common elsewhere. Every year, the community reports back on how it is maintaining those standards. It is an ongoing commitment, not a one time achievement, which is part of why the designation still means something.
For buyers, this shows up in a few practical ways. If you are building new or adding exterior lighting to a property in the area, there are lighting guidelines to be aware of, generally favoring fixtures that point down and stay warm in tone rather than bright and skyward. It is a small adjustment compared to what most people are used to, and most buyers who move here for the quiet and the stars find it is an easy trade to make once they understand what it protects. If lighting plans are part of what you are considering for a property, that is a good conversation to have with the county and with us early, simply so there are no surprises.
Beyond the practical side, this designation shapes the character of the whole valley in a way that is hard to put a price on and easy to fall in love with. Neighbors here tend to already understand why a bright yard light is not a neutral choice, and that shared understanding is part of what makes the night sky here feel communal rather than incidental. Astrotourism brings visitors from well beyond Colorado specifically for what we can see overhead, and locals gather at the observatory for viewing nights throughout the year. It is one of the rare features of a property that everyone in town has agreed, together, to protect.
If dark skies are part of why you are drawn to this valley, that instinct is a good one. Few places anywhere still offer a view like this, and fewer still have organized an entire community around keeping it that way. When we walk a property together, I am always glad to talk through what the designation means for that specific piece of land, whether you are building new, adding on, or simply wondering what the fuss over one small yard light might be about.
