Top 25 Public Observatories

Celestial bodies have long since fascinated humans. From the development of astrology to Niel Armstrong walking on the moon, there is just something about the far reaches of space that awes and inspires us. Looking up at the night sky can be either breath-taking or lackluster, depending on the weather conditions and light pollution in your area. For example, the night sky in New York City is going to look a lot different than the night sky in Montana. In fact, it basically says so in the nicknames, the City that Never Sleeps vs. Big Sky Country. But regardless of where you are in the nation, you are more likely to see the milky way on a clear night out in the country than you are in the middle of a city. So does that mean that city-dwellers are out of luck when it comes to the amateur exploration of astronomy?

Fortunately, it does not.

Anyone interested in learning more about what exists outside of our atmosphere can and should visit an observatory. An observatory is a dedicated building that houses an astronomical telescope for the express purpose of studying natural phenomena and enhancing our understanding of astronomy and other sciences. They are commonly found in areas with little light pollution, and hundreds of them all across the country are open to the public. So if you are interested in learning more about the heavenly bodies that both can and cannot be seen from earth with the naked eye, then head to an observatory to learn, explore, and discover. Who knows, it may just inspire a new passion or hobby for you.

Below is a list of the top 25 public observatories in the United States, organized by state. There may not be an observatory in your backyard, but a little bit of travel can be more than worth your while. So pick an observatory close to you, wait for nightfall, and enjoy the view!

Kitt Peak National Observatory


The desert climate in Arizona means that there are a lot of wide open spaces without a lot of light pollution, and the Kitt Peak National Observatory is is located in an ideal spot for stargazing. 56 miles west of Tuscon, the observatory is positioned on Kitt Peak in the Quinlan Mountains in the Arizona-Sonoran Desert. Groundbreaking astronomical research is conducted there, but it is still open to the public and boasts a very impressive Visitor Center.

The mission of the Kitt Peak Observatory Visitor Center is to “inspire a sense of wonder and awe about the Universe through exhibits, daytime tours, and nighttime public programs” (source). If you are looking to learn more about our position in space and the natural phenomenon occurring lightyears away, then you cannot do much better than Kitt’s Peak Observatory. Both daytime and nighttime activities are available.

Griffith Observatory


Griffith Observatory actually breaks that “no light pollution” rule with its location in the center of one of our nation’s largest cities, Los Angeles. It is, however, positioned on top of a rather impressive peak on the southern slope of Mount Hollywood, bringing it closer to the heavens than the rest of the city of angels is. The fact that you can view the Los Angeles Basin, Downtown Los Angeles, Hollywood, and the Pacific Ocean from its location has made it an incredibly popular hiking destination for celebrities, tourists, and locals alike.

The observatory was opened in 1935 after Colonel Griffith J. Griffith left funds in his will for its creation. Admission to the building and grounds is always free, and there are several portable telescopes set up on the lawn for viewers. Interested parties can even look through the historic Zeiss telescope. If you are planning a trip to Los Angeles or live anywhere in the area, a stop at Griffith Observatory is an absolute must. You can come by during the day for a challenging hike, and then return at night to check out that glorious southern California sky.
