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.
Glowing nights are under 25% moonlight — dark enough to see the Milky Way core from a big park. Bookmark this page and aim for the darkest stretch.
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.
Peaks July 30, 2026 · active Jul 12 – Aug 23
A bright Moon at peak hides everything but the fireballs.
Faint and steady — it overlaps the early Perseids, so late July gives you both.
Debris from Comet 96P/Machholz
Peaks August 12, 2026 · active Jul 17 – Aug 24
Peak falls on dark nights — the faint meteors will show.
The summer classic: warm nights, high rates, and the Milky Way already overhead.
Debris from Comet Swift–Tuttle
Peaks October 21, 2026 · active Oct 2 – Nov 7
A bright Moon at peak hides everything but the fireballs.
Halley's second pass of the year — fast meteors with long trains.
Debris from Comet Halley
Peaks November 17, 2026 · active Nov 6 – Nov 30
Some moonlight, but the brighter meteors cut through it.
Usually modest, but the parent comet produces a storm roughly every 33 years.
Debris from Comet Tempel–Tuttle
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.

Photographs are served from nps.gov at gallery size (~50 KB each) — we link to the original rather than re-hosting it. Credit belongs to the photographers named on each frame.
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.
A new moon. The Milky Way core is naked-eye visible when the moon is under about 25% lit. Tonight it is 99% lit; the next new moon is August 13 - the calendar above highlights the darkest nights.
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.
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.
