Dark Sky Reserves: Top 15 Global Destinations for Stargazing

The International Dark-Sky Association (IDA) certifies locations that demonstrate exceptional commitment to preserving the night sky. There are several designations:

• Dark Sky Parks — Public lands with exceptional starry skies and programs for night sky education
• Dark Sky Reserves — Large areas with a dark core surrounded by a protected buffer zone
• Dark Sky Sanctuaries — The most remote and darkest places on Earth

These aren't just marketing labels. Certified locations must prove Bortle Class 3 or darker skies, implement lighting ordinances, and provide public stargazing access.

The Astro Café at Mt. John Observatory is the only place I've had a flat white while watching the sun set behind the Southern Alps, then stepped outside to see the Milky Way rise.
