Two US Dark Sky Parks Worth a Night Trip

A Dark Sky Park is a place certified by DarkSky International for exceptional night skies and the lighting policies that protect them. In the US, two dark sky parks stand out for a trip: Bryce Canyon, rated Gold Tier, and Waterton-Glacier, the first International Dark Sky Park to cross a national border.

What a Dark Sky Park Is

A Dark Sky Park holds a certification from DarkSky International for two things together: an exceptional night sky and lighting policies that protect it. The formal name is International Dark Sky Park, the title both Bryce Canyon and Waterton-Glacier carry.

The title tells you a park guards its darkness on purpose. Your own night still depends on the moon phase, the season and the viewpoint you pick.

Two US dark sky parks are worth planning a trip around:

• Bryce Canyon. Gold Tier, open 24 hours, with ranger telescope programs, full moon hikes and an annual astronomy festival in June.
• Waterton-Glacier. The first transboundary International Dark Sky Park, which includes Glacier National Park.

Pick Bryce Canyon for its ranger telescope programs, full moon hikes and June festival. Pick Waterton-Glacier if a Glacier visit is already on your list and you want a night under the first International Dark Sky Park to span a national border. For more on dark sky parks, see DarkSky International's site.

How Dark Sky Park Certification Works

The lighting policies are part of the standard, so the designation describes how a park manages its own lights as well as how dark its sky is.

Certification can arrive in stages. Waterton-Glacier held provisional status for four years before it earned full certification. Certification also comes in tiers, and Bryce Canyon holds the Gold Tier designation.

Bryce Canyon, a Gold Tier Dark Sky Park

Bryce Canyon became a Gold Tier International Dark Sky Park in 2019, according to the National Park Service. Its high elevation, clean air and remote location give it some of the darkest skies in the country. On a clear night near the new moon, you can see thousands of stars and the band of the Milky Way stretching across the sky.

The park is open 24 hours a day, so you can drive to a viewpoint whenever the sky looks right. Viewpoints have paved, flat surfaces open to everyone, while trails vary.

Viewpoints for Stargazing

• Sunrise Point: a short walk leads to a nearly 360 degree view with little light pollution from Tropic and Bryce Canyon City.
• Inspiration Point: close to its parking lot, which helps on a cold night, with 360 degree views from the higher viewpoints.
• Whiteman Bench Picnic Area: at mile 9.5 of the 18-mile road, one of the darkest places in the park by darkness readings.
• Yovimpa Point: a view south with only distant light pollution from Page, Arizona.
• Sunset Point and Paria View: two more recommended viewpoints for stargazing.

Night Photography with Hoodoos

For hoodoos in the foreground of night photos, Queen's Garden Trail has hoodoos to the south, east and west. The Navajo Loop frames the sky with tall fins of rock and hoodoos to the east and north.

Ranger Programs

Ranger-led telescope programs run on some nights, depending on the time of year and day of the week. Full moon hikes are another ranger program, for seeing the park under the bright light of a full moon. Stop by the visitor center to see which programs fall during your visit, and read the Stargazing at Bryce Canyon guide for more viewing detail.

Waterton-Glacier International Dark Sky Park

Waterton-Glacier was the first International Dark Sky Park to cross a national border. The National Park Service announced its provisional designation in 2017, and full certification followed in 2021. For a US traveler, the designation covers Glacier National Park.

Bryce Canyon and Waterton-Glacier Compared

Choose Bryce Canyon if you want ranger programs, a June festival and paved viewpoints you can reach at any hour. Choose Waterton-Glacier if you are already heading to Glacier and want to add a night under the first transboundary dark sky park.

Timing, Moon and Gear for Dark Sky Parks

Plan a dark sky park visit around a new moon if you want the most stars.

Moon Phase

Near a new moon, the moon sets with the sun and does not compete with the stars for brightness. If you would rather see the landscape lit up, come near a full moon instead, and at Bryce, time the trip with a ranger-led full moon hike.

Season

June is one of the best months at Bryce Canyon, and it is when the park holds its Annual Astronomy Festival. The 2026 festival ran June 11 to 13 and was free with park admission.

Some part of the Milky Way is visible year-round at Bryce's latitude. The galactic center, the most vivid part, shows best from June through August if you want it soon after sunset.

Winter visitors can see the outer bands of the Milky Way, which are much dimmer. Very few people have stood somewhere dark enough to see this winter Milky Way.

Gear

Bring a red flashlight, a warm layer and a tripod if you plan to photograph hoodoos under the stars.

At Dark Light Collection, we are building glass pyramids on private land about 15 minutes from Bryce Canyon National Park and within 15 minutes of Glacier's West Entrance, opening in 2027. Each pyramid has a personal deck telescope and a king bed positioned for sky-gazing. Read why dark skies matter.

Night-Sky Etiquette in Dark Sky Parks

Good night-sky manners mean keeping light low and engines off.

• Use a red light, and point it at the ground.
• Dim your headlights as you pull into a viewpoint, then switch them off once parked.
• Keep phone screens on their lowest brightness.
• Do not idle your engine or run a generator. Bryce does not permit either in park parking lots.
• Keep pets on paved surfaces and on a leash no longer than 6 feet at Bryce, and do not leave them in a vehicle while you hike.
• Talk quietly near telescopes and photographers.
