The Best Dark Sky Parks In The United States

Step far enough from the nearest city and the night sky changes completely. Thousands of stars crowd into view, planets resolve into steady points of light, and on a clear night the Milky Way arcs overhead like a band of pale smoke. Protecting that view, for astronomers and first-time stargazers alike, is the whole point of a Dark Sky Park.

DarkSky International, formerly the International Dark-Sky Association, certifies these places through its International Dark Sky Places program. A Dark Sky Park is a public or private space with an exceptional quality of starry nights and a protected nocturnal environment, managed for its scientific, natural, educational, cultural, and public value. In plain terms, it is dark enough, and far enough from light pollution, that the stars come out in force. The idea has caught on fast: the program has grown from a single certified site in 2001 to more than 250 places worldwide by late 2025.

Here are eight of the best dark sky parks in the United States for anyone who wants to look up and really see the night.

1. Big Bend National Park
2. Grand Canyon National Park
3. Glacier National Park
4. Cherry Springs State Park
5. Arches National Park
6. Headlands International Dark Sky Park
7. Mayland Earth-to-Sky Park And Bare Dark Sky Observatory
8. Anza-Borrego Desert State Park

Big Bend National Park

Big Bend, in the far southwest corner of Texas, wraps around a giant curve of the Rio Grande and takes in both the Chisos Mountains and a vast stretch of the Chihuahuan Desert. Its isolation is its superpower. Sitting hundreds of miles from any major city, the park carries almost no light pollution, and the National Park Service Night Sky Team has measured its skies as the darkest in the lower 48 states. DarkSky International certified Big Bend as a Gold-tier International Dark Sky Park in 2012, and in 2022 the surrounding Greater Big Bend International Dark Sky Reserve, spanning Texas and Mexico, became the largest dark-sky-certified area in the world. Rangers run regular night-sky programs for the visitors who make the trek out to see it.

Grand Canyon National Park

The Grand Canyon is one of the most visited national parks on Earth, and after dark it doubles as one of the best places in the country to see the stars. Getting there took work. With more than 5,000 light fixtures across the park, the National Park Service earned provisional dark sky status in 2016, then spent three years retrofitting its lighting to reach full certification in 2019, timed to the park's centennial. Arizona's high, dry air and mostly clear skies do the rest, and with almost no settlement around the canyon rim, there is little to spoil the view.

Glacier National Park

Glacier National Park, high in the Rocky Mountains of Montana, shares its dark skies with Canada. In 2017 it joined with Waterton Lakes National Park across the border to form the Waterton-Glacier International Peace Park, the first International Dark Sky Park to span two countries. The park's high elevation lifts it above much of the haze and glow of the lowlands, and rangers lead night hikes and twilight walks to make the most of the clear mountain skies.

Cherry Springs State Park

On the East Coast, the best dark skies belong to Cherry Springs. Pennsylvania named it the state's first dark sky park in 2000, and DarkSky International certified it as an International Dark Sky Park in 2008, making it the second-oldest such park in the world after Utah's Natural Bridges. Perched on the Allegheny Plateau and ringed by the Susquehannock State Forest, the 82-acre park offers a nearly 360-degree view of the sky and ranks among the very best places in the country to see the Milky Way. On the right night, the northern lights put in an appearance too.

Arches National Park

Utah is a stargazer's dream, the only state where every national park holds dark sky certification, and Arches is one of its standouts. Certified as an International Dark Sky Park in 2019, the park pairs its famous red-rock formations with genuinely dark skies, so a landmark like Delicate Arch can be framed against a sky thick with stars. Arches hosts an annual astronomy festival and regular ranger-led night programs that turn stargazing into a shared event.

Headlands International Dark Sky Park

Michigan's Headlands sits on the wild northern tip of the Lower Peninsula, 600 acres of old-growth forest fronting more than two miles of undeveloped Lake Michigan shoreline. When it was certified in 2011, it became just the sixth International Dark Sky Park in the United States and the ninth in the world. Far from any city glow, its dark meadows and shoreline open straight onto the sky, and on active nights the aurora borealis, a rare treat this far south, glows over the lake. Little wonder it has become a magnet for amateur astronomers.

Mayland Earth-to-Sky Park And Bare Dark Sky Observatory

When DarkSky International certified the Mayland Earth to Sky Park in 2014, it became the first International Dark Sky Park in the southeastern United States. The site sits about six miles west of Spruce Pine, North Carolina, high in the Blue Ridge Mountains and well away from city lights. It is also a working astronomy center. Its Bare Dark Sky Observatory houses one of the largest public telescopes in the Southeast, and the site later added the Glenn and Carol Arthur Planetarium, a 36-foot dome that hosts weekly shows.

Anza-Borrego Desert State Park

Anza-Borrego earned its International Dark Sky Park designation in 2018. California's largest state park spreads across the Colorado Desert of southeastern California, where a dry desert climate and the absence of big cities make for excellent viewing. It helps that the neighboring town of Borrego Springs became an International Dark Sky Community back in 2009, switching to low-emission lighting and fixtures so its glow barely touches the stargazing next door.

International Dark Sky Places In The United States

The eight parks above are only a starting point. The list below rounds up the International Dark Sky Places certified across the United States, from the first parks and communities of the early 2000s through the most recent designations in 2025. It spans all five categories DarkSky International recognizes: dark sky parks, communities, reserves, sanctuaries, and the newer urban night sky places. The organization passed 250 certified places worldwide in late 2025, and the pace shows no sign of slowing.
