After dark & night sky things to do in Des Moines
After-dark and night-sky things to do in Des Moines: 9 of them, from Drake Municipal Observatory, Ashton Observatory (Des Moines Astronomical Society) and Annett Nature Center observation tower.

They spread across Drake, Mingo (Ashton Wildwood County Park), Jasper County, Indianola (near Lake Ahquabi), Warren County, South Des Moines, Polk County and 5 more areas, so two or three can make a whole afternoon. Every entry is hand-vetted against real sources — not scraped off a top-ten list or averaged out of crowd ratings.

Drake Municipal Observatory
A 1921 limestone observatory hidden inside a public golf course, where the cremated ashes of astronomer Daniel Morehouse — who discovered Comet Morehouse in 1908 — and his wife Myrtle are interred inside the rotunda wall, marked by a plaque. Students working the historic 8.25-inch refractor have reported flickering lights, doors bursting open, and cold spots, including incidents witnessed by longtime lecturer Herb Schwartz. Free public lecture-and-viewing nights run Friday evenings spring through fall.

Ashton Observatory (Des Moines Astronomical Society)
A volunteer-run county-park observatory with two domes, a 16-inch Newtonian reflector and a 14-inch Schmidt-Cassegrain, sitting under genuinely dark Jasper County skies about 20 minutes northeast of the city. Public nights run free every Saturday April through October (skipping the first Saturday of the month), starting around sunset or 8:00 p.m. On the 2nd and 4th Saturdays an 8:00 p.m. classroom program runs first; other nights go straight to the telescopes. Weather permitting, you peer at the Moon, planets, and bright nebulae through the big glass, and you can bring your own scope to set up on the dark field.

Annett Nature Center observation tower
A 160-acre Warren County nature preserve on a hillside ringed by farmland, with a 30-foot observation tower that central-Iowa stargazers favor as a dark-sky perch just south of the metro. Sitting next to Lake Ahquabi State Park and away from city glow, it stays surprisingly dark for being this close to Des Moines, though the park grounds close at 10 p.m., so it's an evening-into-night spot rather than an all-nighter. Climb the tower platform after sunset with binoculars or a telescope and you can pick out constellations, meteor showers, and the occasional planet. (The nature center building keeps weekday daytime hours, but the trails and tower are open until close.)

Full Moon Hike at Fort Des Moines Park
Polk County Conservation leads a Full Moon Night Hike through Fort Des Moines Park, walking the trails after dark under the light of the full moon. You'll discover the sights, sounds, and wildlife that come alive at night, and the outing wraps with a campfire for roasting marshmallows and making s'mores. The hike is free, but registration is required, and it all departs from Shelter #3 close to downtown.

Iowa Star Party at Whiterock Conservancy
Whiterock Conservancy is a 5,500-acre nonprofit land trust along seven miles of the Middle Raccoon River valley, with some of the darkest skies in Iowa thanks to its distance from city lights and Coon Rapids' dark-sky-compliant lighting ordinance. Each fall the Ames Area Amateur Astronomers and Des Moines Astronomical Society host the multi-night Iowa Star Party here, and there's a free public viewing night where you can wander among dozens of telescopes after a short intro to the sky. On a clear night you can actually see the Milky Way arc overhead, plus galaxies, nebulae, and planets through the assembled scopes.

Star Parties at the Science Center of Iowa
The Science Center of Iowa runs free Solar and Star Parties where staff and volunteers set up high-powered telescopes for the public to view the Sun, Moon, planets, double stars and meteor showers. Solar parties pop up downtown by the museum during the farmers market, while evening star parties rotate among the Science Center, Drake Municipal Observatory and the Ashton Observatory out near Mingo. Pair it with the center's 50-foot domed Star Theater planetarium and its live "Iowa Skies Tonight" sky tour, and you get an indoor immersive sky show plus real telescope time, with guides on hand to help you actually find targets. No tickets or registration required for the star parties.

Valle Drive-In
Iowa's oldest drive-in, running since 1949, sits about 30 miles east of Des Moines and still throws double features under the open sky from spring through October. A March 2025 tornado tore up the screen, and the crew famously reopened by showing 'Twister' once it was rebuilt. Gates open at 6:30 p.m. so you can settle in before the picture starts at dusk, with sound piped through your car radio on FM 88.7.

Candlelight Concerts at the World Food Prize Hall of Laureates
A string quartet plays Coldplay, Queen, Metallica or Vivaldi by the glow of thousands of flickering LED candles inside a restored 1903 Beaux-Arts library turned museum. The room is crowned by a stained-glass globe and marble detailing, so the music lands in a setting far stranger and grander than a normal concert hall. Each seating is about an hour, with evening shows usually starting between 6:30 and 8:30 p.m. depending on the program.

Ashton Observatory Public Saturday Nights
Run by the Des Moines Astronomical Society inside a dark-sky county park northeast of the metro, Ashton opens for free public stargazing every Saturday evening from April through October. Away from city light, the sky is dramatically darker than anything you'll see downtown, and on the 2nd and 4th Saturdays there's a classroom program before viewing. Telescopes and volunteers are on hand to help you find deep-sky objects.
