DARK SKIES · PARK BY PARK

Stargazing in the national parks 🌌

The moon decides what you'll see: around the new moon the Milky Way core is naked-eye visible from most big parks. Below — every park with a hand-curated night-sky guide, and tonight's moon so you can time the trip.

Is this year's peak worth the drive?

Every site lists the dates. The dates alone don't tell you much — a peak of 150 meteors an hour under a full Moon shows you almost nothing, while a quiet 20 an hour on a dark night is a real show. So each shower below carries the Moon it will actually have, computed for that exact night.

A bright Moon at peak hides everything but the fireballs.

Geminids

Peaks December 14, 2026 · active Dec 4 – Dec 20

150meteors/hr at best

Peak falls on dark nights — the faint meteors will show.

The strongest shower of the year, and the only major one from an asteroid.

Ursids

Peaks December 22, 2026 · active Dec 17 – Dec 26

10meteors/hr at best

A bright Moon at peak hides everything but the fireballs.

Small, northern, and easy to have to yourself on the solstice.

The hourly figure is the zenithal hourly rate — the idealised count under a perfect dark sky with the radiant straight overhead. Real counts are always lower, and lower still near a town. Peak dates shift by up to a day year to year.

OFFICIALLY PROTECTED SKIES

17 parks certified as Dark Sky Places

A certification isn't a rating of how dark a night looks — it's a commitment: the park has replaced its lighting, measured its sky and agreed to keep it that way. That makes it the most reliable single signal for choosing where to point a telescope.

List read from the National Park Service on 2026-07-20 and filtered to national parks. We store no certification years or designation types because that page doesn't publish them — and guessing them would be worse than leaving them out. New parks are certified regularly, so a park missing here means not on our verified list, not that its sky is poor.

QUICK ANSWERS

Frequently asked

What moon phase is best for stargazing?

A new moon. The Milky Way core is naked-eye visible when the moon is under about 25% lit. Tonight it is 20% lit; the next new moon is October 11 - the calendar above highlights the darkest nights.

When can I see the Milky Way in a national park?

Roughly March through October in the lower 48: the galactic core rises after dark and sits highest around midnight in summer. Pick a night from the dark window in the calendar and check the park's cloud forecast in the table above.

Do I need a telescope?

No. The Milky Way, meteors and satellites are naked-eye sights; binoculars add star clusters and Jupiter's moons. The one essential is a red-light headlamp - it preserves your night vision.

Which parks have a stargazing guide here?

Acadia National Park, Arches National Park, Badlands National Park, Big Bend National Park, Canyonlands National Park, Grand Canyon National Park, Yosemite National Park, Zion National Park. Each guide computes sunrise, sunset and the moon for that park's own timezone.
