When was the last time you really saw the stars? Not just a handful of faint pinpricks—but the kind of sky that makes you feel like a speck in the universe. Tucked into Hocking Hills State Park, John Glenn Astronomy Park (JGAP) delivers that rare, cosmic thrill—no telescope required.
Named after the Ohio-born astronaut and American hero, this astronomy park turns an ordinary night into an interstellar experience. Whether you’re a lifelong space geek or just someone looking for a screen-free evening with a little wonder sprinkled in, this place has a way of pulling you in and leaving you starstruck.
What We Love
A Dark Sky Dream Come True
Thanks to the remote setting in southeast Ohio, far from city light pollution, JGAP is one of the best places east of the Mississippi for stargazing. On a clear night, you’ll spot the Milky Way stretching overhead like a cosmic highway, along with planets, constellations, and maybe even a meteor or two.

Free Public Telescope Nights
If you show up during one of their guided events (typically Friday and Saturday evenings in summer), local astronomers will guide you through the night sky using high-powered telescopes. Saturn’s rings? Jupiter’s moons? They’re all fair game—and yes, they really do look like the pictures.

Solar Viewing During the Day
Visit during daylight hours, and you’ll find a special solar telescope that lets you safely peek at the sun’s surface. Bonus: the stone plaza is perfectly aligned with seasonal markers, like solstices and equinoxes, turning the space into a giant outdoor calendar.
Interactive Learning for All Ages
Plaques around the plaza help you identify key constellations, and the staff loves fielding questions—from “What’s that bright dot?” to “Could I really survive on Mars?” It’s a family-friendly science night with a side of wow.
A Tribute to Exploration
The park honors John Glenn’s legacy not just in name, but in spirit. It’s a celebration of curiosity, adventure, and looking up—both literally and figuratively.

Atmosphere & Setting
It’s peaceful here in a way you don’t expect. The park is tucked between tall pines and rolling hills, with a sleek, circular plaza at its center. The open-air design gives you an unobstructed dome of sky, and as twilight deepens, the buzz of crickets mixes with the low murmur of visitors settling in with lawn chairs and blankets. There’s no flashy lighting or music—just the rustle of wind and the hum of anticipation as the first stars pop into view.

Value (Is It Worth It?)
Absolutely—and it’s free! The park is open 24/7, and while guided programs are seasonal, there’s no admission charge any time of year. You’ll want to spend about 1–2 hours here, but many linger longer during events. It’s a dream spot for couples, families with curious kids, and nature-loving retirees alike. Just bring your sense of wonder—and maybe a thermos of cocoa.
Other Considerations
Bring a Flashlight (But Make It Red)
Red light preserves your night vision, and white light is discouraged during evening programs. Many guests bring headlamps or flashlights with red filters to navigate the short gravel paths.
Weather and Timing
Cloudy skies mean little visibility, so check forecasts before you go. Spring through fall tends to be best, but winter visits offer the crispest constellations for the bold and bundled-up.
Parking and Terrain
There’s a small lot near the plaza and overflow nearby. The main area is flat and partially paved, but bring good shoes if it’s been raining—things can get a little muddy.
No Food or Bathrooms On-Site
There are no concessions or restrooms directly at the park, so plan ahead. The closest facilities are about 10 minutes away at Old Man’s Cave or other Hocking Hills landmarks.

When it comes to finding awe in the everyday, few places deliver quite like John Glenn Astronomy Park. It’s a reminder that above the hustle and glow of our busy lives, there’s an entire galaxy just waiting to be rediscovered.
