If you're going stargazing in the USA, American National Parks offer some of the darkest skies under which to get fantastic views of the cosmos.
Whether you're observing deep-sky objects with a telescope, or capturing the night sky with a spot of astrophotography, or observing naked-eye sights such as meteor showers and conjunctions, the darkness afforded by these expansive sites far from light pollution makes National Parks a great option.
Here are 10 American National Parks – most but not all official Dark Sky Parks – that are free from urban light pollution, and which offer some of the darkest and clearest night skies in the world for stargazing.
If you want to bring your telescope with you, you'll need something compact and portable. Read our guide to the best travel telescopes for astronomy.
