Summer is finally upon us and, with camping adventures and weekend getaways slowly filling in our calendars for the next 16 weeks, now is the perfect time to expose the National Parks’ “dark” secret: that one of the most magical and immersive experiences you can have at a national park happens after the sun goes down.
We’re absolutely the first to recommend a daytime visit to a National Park, but the truth is you’re really only getting half the story. When the sun goes down, the plants, wildlife, and geology of the natural parks become almost otherworldly, lit up by stars that millions of people in urban areas never get to experience.
Initially, the preservation of this dark “other half” of the U.S. National Parks was almost accidental; as the Park Service worked to protect the scenery, the natural and historic objects, and the wildlife of park areas, night sky preservation sort of just happened. But a growing awareness of light pollution and its effects has led to the establishment of the Park Service's Natural Sounds and Night Sky Division, specifically dedicated to saving our dimming night skies by monitoring light levels and creating after-dark educational programs.
But maybe you’re not an amateur astronomer. Why should you risk shin-bruises to hang around a national park when the sun goes down? Because, as Nordgren puts it, “By day, you’d be shoulder-to-shoulder with crowds and cars, but when you go out at night, you’ve got [the park] to yourself. It really gives people a flavor of what it must have been like in these parks back in the 1930s when it was just you and nature.” All that beauty without hordes of tourists? What more could you ask for?
So how can you get in on this?
More and more parks have after-dark programs, from lectures to stargazing nights and night hikes. Rangers are able to connect visitors to the flora, fauna, and geology of the parks at night, as well as to the constellations above. In fact, big events like night sky festivals and star parties are becoming so common that it’s getting hard to keep track of it all. Luckily, the parks coordinate to make sure they aren’t scheduling events on the same weekends, making a summer of park-hopping across the U.S. for night sky adventures entirely possible (advisable, even!).
You can always feel free to call or email your closest park to find out about their evening ranger programs (and to purchase tickets to larger events), but here are a few that we’re especially looking forward to this year:
June 21—June 24
Bryce Canyon has the distinction of having hosted the first star party back in 1969. The tradition has continued because Bryce's inky dark skies and convenient location near both Salt Lake City and Las Vegas makes it an ideal spot. In fact, the star parties become so popular that they've evolved into full-blown Astro Festivals. Additionally, Bryce hosts monthly night hikes and regular astronomy education programs followed by stargazing.
Glacier National Park
West Glacier, Montana
July 14, July 28, August 25
Glacier’s Logan Pass star parties may not be as long-running as Bryce Canyon’s, but they are just as famous. In the past, the Pass has seen crowds of up to 500 eager to experience the summer Milky Way against Glacier’s ultra-dark sky, so this year the park is hosting four different star parties to accommodate the ever-growing number of participants. Glacier also runs night sky programs regularly throughout the year.
Acadia National Park
Mount Desert, Maine
Stargazing at Badlands? Sure. Glacier? Definitely; we expect great stars in places with famously wide-open skies, but people don’t often think of the East Coast as somewhere you can go to see the Milky Way. Acadia National Park is determined to challenge that idea. Acadia’s Night Sky Festival, set in the late fall between the heat of summer and the frenzy of leaf-peeping season, features speakers, workshops, and hands-on experiences that appeal to a full range of visitors, from children to aspiring astronomers. The park also hosts regular dark sky events throughout the year.
Great Basin National Park
September 21–September 23
Great Basin’s annual Astronomy Festival features ranger talks, telescope viewing and stargazing. Last year the park’s new research observatory opened in late August and while the observatory isn’t technically part of the Astronomy Festival, it's accessibility is sure to be a draw for any amateur astronomers. The state-of-the-art facility gives small universities and even members of the public a chance to purchase a night on the telescope and experience the distant galaxies like professional astronomers do.
Other Dark Sky Festivals taking place this year:
Grand Canyon National Park, Craters of the Moon National Monument, Badlands National Park, Sequoia and Kings Canyon National Parks, Lassen Volcano National Park, and Capitol Reef National Park.
And if you’d rather strike out on your own?
Maybe you’re busy the weekend of the closest star party, or maybe you'd prefer a more solitary experience. Here are a few of Dr. Nordgren’s tips for exploring parks (or really any dark sky area—the International Dark Sky Association’s list includes a few spots that aren’t technically National Parks) at night on your own:
“Check to find out what the phase of the moon is going to be. If the moon is not up, that’s when the sky is its darkest and you’ll see what looks like a million stars.
“If the moon is up, then that’s an opportunity to take advantage of the light and go for a moonlit hike. When a full moon is up, it will light things up like daylight once your eyes are night-adjusted.
“Either way, get out there and let your eyes really adjust to the darkness. If you must take a headlamp, use one that has a red light on it that won’t hurt your night vision as much. Just go out, especially in summer when the nights are warm, put a blanket out, and just lay down and look up at the sky. Give yourself a half hour with no lights at all—don’t look at your iPhone, don’t look at your watch—and your eyes will be night-adapted. Then, if you’re lying down and looking straight up, your entire field of vision will become filled with stars.”
