25 of the Best Observatories in the U.S. to Visit in 2021
While everyone can enjoy the wonders of the night sky from their backyard or a nearby dark sky destination, there’s nothing quite like visiting an observatory. Observatories offer awe-inspiring views of objects in our solar system and deep space.. Often what we can see at these astronomy centers is better than we’ll ever see on our own, even if we own a telescope.
Additionally observatories usually include programs where amateur or professional astronomers can teach you about all those amazing things you’re seeing. But wait: How do we know which observatory to visit? Which are the best observatories in the U.S.?
In this post, you’ll learn about the 25 best observatories across the U.S. from the East Coast to the West – from the Pacific Northwest to New England to the Southeast. Whether you live near one of these great observatories or are planning a trip, consider spending an evening at one of these – the 25 best observatories in the U.S.
How These Observatories Were Chosen: To create this list of the best observatories, best planetariums, and best science museums across the USA, Kuoni compared 117 locations to find the top 25 with the best average review score on TripAdvisor. These locations were then re-ordered by highest volume of ‘Excellent’ reviews and cross-referenced with whether they have been awarded a Certificate of Excellence.

I would like to visit every observatory within reach, as I vacation around North America.

Ralph Buice Jr Observatory has its own light pollution. One had better prepare themselves to “not see” the Milky Way standing outside most of the observatories listed(especially the ones east of the Mississippi). You can see the brightest stars , planets and moon but for the most part the power of these telescopes is lost due to light pollution. Thank you, Valerie for this site but I thought it only fair to let people know what is happening.
