Why I added it
Boulder is not one of the official 21. I include it because it is practical for visitors, has real local dark-sky policy history, and sits on the natural approach to the mountain trail.
How to use this stop
This is an independent addition, not an attempt to redraw the official trail. It belongs here because a road trip is more useful when it can acknowledge excellent night-sky places just outside the certification map.
Verify before driving at night
- Legal parking and nighttime access.
- Weather, road and seasonal closures.
- Private-property boundaries.
- Local fire, wildlife and land-management restrictions.
- Whether a current public program actually exists before promising one to your group.
