You Can See the Northern Lights in Idaho and Most People Have No Idea

Solar Maximum Peaks Through 2026

The sun is nearing the peak of its 11-year activity cycle, and that means the Northern Lights are more frequent and more intense than they have been in over a decade.

Solar physicists expect the most frequent and intense Northern Lights displays starting in 2024 and potentially lasting through 2026. For most Americans, catching the aurora means booking a trip to Alaska or Scandinavia.

But there is a place in the lower 48 where the skies are dark enough to see it, and the timing could not be better.

1,416 Square Miles of Darkness

The Central Idaho Dark Sky Reserve spans 1,416 square miles near the Sawtooth National Recreation Area and was designated on December 18, 2017.

It is the first International Dark Sky Reserve in the United States and one of just 12 such reserves worldwide.

The International Dark-Sky Association also granted the reserve gold-tier status, the highest ranking for night sky quality.

The reserve stretches from Stanley to Sun Valley, covering some of the most rugged and least developed land in the country.

80 Percent Lost the Stars

Light pollution now hides the Milky Way from 80 percent of Americans, according to a global atlas of artificial night sky brightness.

“We’ve got whole generations of people in the United States who have never seen the Milky Way,” said Chris Elvidge, a scientist with NOAA’s National Centers for Environmental Information.

Places where you can still see our galaxy with the naked eye are vanishing. Central Idaho is one of the last.

Mountains Kept Developers Away

The challenging topography of the Sawtooth Range has historically discouraged the development of significant infrastructure, so the land has largely resisted electrification.

Central Idaho is therefore one of the last large pools of natural nighttime darkness left in the United States. No highways cut through the wilderness.

No cities glow on the horizon. The darkness here is not protected by policy alone.

It is protected by geography.

Ketchum Led the Fight

Ketchum has had a dark sky ordinance since 1999. Hailey passed a municipal dark sky ordinance in 2002, Sun Valley in 2004, Blaine County in 2010, and Custer County in 2010.

These regulations require shielded streetlights and limit the brightness of outdoor fixtures.

The city reached out to residents to educate them about the need for dark skies and committed to bringing all municipally-owned lighting into compliance. Two decades of effort made the reserve possible.

Stanley Has 62 People

When you arrive at the entrance of Stanley for the first time, you shake your head at the sign that greets you: Stanley, Idaho, population 62.

The town sits at the gateway to the Sawtooth Wilderness, surrounded by jagged peaks that block any stray light from distant cities.

Redfish Lake and the entire Stanley area have almost no light pollution, making it ideal for stargazing and Milky Way photography. You do not need a telescope here.

You just need to look up.

Aurora Reaches Northern Idaho

The Northern Lights can be seen in Idaho. Bonners Ferry, Priest Lake, Sandpoint, and Coeur d’Alene all have dark skies perfect for spotting the aurora when conditions are right.

During the solar maximum, strong geomagnetic storms push the aurora farther south than usual. Solar Cycle 25 is moving past its peak, but strong solar storms and vivid auroras may still lie ahead in 2026.

If you time it right, you can watch the sky turn green from Idaho soil.

Four Dark Sky Sites Now

Idaho is home to a dark sky reserve and three dark sky parks.

Idaho’s International Dark Sky Parks include Craters of the Moon National Monument and Preserve, Bruneau Dunes State Park, and City of Rocks National Reserve.

Each offers ranger-led programs, star parties, and camping under skies most Americans will never experience. The state has quietly built one of the best astrotourism networks in the country.

Bruneau Dunes Has Big Telescopes

Bruneau Dunes State Park encompasses 4,800 acres and hosts two observatories, including a 25-inch telescope that is one of the largest publicly accessible telescopes in the Northwestern U.S.

In 2023, the park opened an additional observatory housing an even more powerful CDK 700 telescope.

The observatory is open to the public on Fridays and Saturdays from late March through mid-October, with astronomy presentations and telescope viewing. Admission is five dollars.

Redfish Lake Mirrors the Sky

If you want to find yourself under one of the darkest night skies with crystal clear alpine lakes, head north from Sun Valley over Galena Summit to Redfish Lake.

The still water reflects the Milky Way like a mirror, doubling the number of stars you see. If you get lucky, you may even catch the Northern Lights.

Photographers travel from around the world to capture this scene. In summer, you can camp at the lake and watch the show all night.

The Clock Is Ticking

Scientists predict the current solar maximum will peak between 2024 and 2026, possibly the most intense in decades. After that, solar activity will decline, and aurora displays will become weaker and less frequent.

If you have been waiting for the right time to chase the Northern Lights without leaving the country, that time is now. Central Idaho is ready.

The sun is cooperating. And after 2026, you will have to wait another decade for skies like these.

Visiting Central Idaho Dark Sky Reserve, Idaho

The reserve covers a vast area between Stanley and Sun Valley, accessible via Idaho State Highway 75.

Stanley makes the perfect base camp for experiencing the reserve, with lodging options open year-round including the Stanley High Country Inn.

July is the best time to see the Milky Way in Idaho, though the season runs from February to November. Time your visit around the new moon for the darkest skies.

There is no entrance fee for the reserve itself, and you can stargaze from pullouts along Highway 75 or from campgrounds near Redfish Lake.
