Planning Tips

Go on the new moon; the darkest skies — and the best Milky Way views — come when the moon is absent. Use a red flashlight and give your eyes 20–30 minutes to fully adjust to the dark. You don't need a telescope; the naked eye reveals the Milky Way at a truly dark site, and binoculars add a lot. Check the season — the bright core of the Milky Way is best from late spring through early fall in the Northern Hemisphere.

Frequently Asked Questions

What is a dark sky park?

A dark sky park is a place certified for its exceptionally dark, high-quality night skies and its efforts to reduce light pollution. DarkSky International awards this designation to qualifying parks, monuments, and sanctuaries.

When is the best time to go stargazing?

On a clear night around the new moon, when there's no moonlight to wash out the stars. For the bright core of the Milky Way, aim for late spring through early fall.

Do I need a telescope to enjoy a dark sky park?

No. At a truly dark site, the Milky Way and thousands of stars are visible to the naked eye. Binoculars enhance the view, and a telescope is a bonus rather than a requirement.

How do I protect my night vision?

Use a red flashlight instead of white light, and give your eyes 20 to 30 minutes in the dark to fully adjust. Avoid looking at your phone screen, which resets your night vision.

How do I keep track of the sites I've visited?

A printable dark sky parks passport — a curated checklist, a detail page for each site, suggested routes, and achievement badges — makes it easy to mark off each one.
