Hocking Hills holds some of the darkest skies remaining in Ohio. While most of the state contends with light pollution from Cleveland, Columbus, and Cincinnati, the forested ridges and deep gorges of Hocking County block ambient light in ways that make naked-eye stargazing genuinely rewarding — and telescopic viewing exceptional.
John Glenn Astronomy Park
Opened in June 2018 and named for the astronaut and Ohio senator, the John Glenn Astronomy Park sits just 0.9 miles west of the Old Man's Cave Visitor Center on State Route 664. The Friends of Hocking Hills State Park raised over $1 million for construction and continue to operate the facility on a remarkably lean budget of under $25,000 per year.
The centerpiece is a 28-inch telescope housed in a roll-off roof observatory — one of the largest publicly accessible telescopes in Ohio. Guided programs run on clear Friday and Saturday nights from early March through late November, beginning approximately 30 minutes after sunset. Programs are free but a parking pass is required — register at registration.jgap.org (limited to 70 cars per night, so register early for popular events).
The park is open 24 hours a day, 7 days a week, year-round for independent stargazing with personal equipment. Even without a telescope, the observing pads offer excellent dark-sky viewing. December through February has no guided programs but offers some of the darkest, clearest skies of the year for self-guided observation.
Best Cabin Locations for Stargazing
Not all Hocking Hills cabins are equal for night sky viewing. The key variable is canopy density — a cabin surrounded by dense forest offers incredible privacy but limited sky exposure. For stargazing, prioritize:
Ridge-top properties: Cabins perched on ridges rather than nestled in valleys offer the widest sky views. The elevation gets you above the gorge canopy and reduces light interference from neighboring properties.
Properties south of Logan: The town of Logan generates the most light pollution in the area. Properties located south along SR-664 toward Old Man's Cave — closer to the astronomy park itself — sit in the darkest zone.
Properties with open decks or clearings: A hot tub under an open sky is the quintessential Hocking Hills stargazing experience. Many cabin listings specifically mention sky visibility from the hot tub or deck — search for these features when booking.

For JGAP programs, bring a red flashlight (white light ruins night vision for everyone on the observing pad), warm layers even in summer (clear nights can be surprisingly cool, and you will be standing still), a blanket or camp chair for comfortable viewing, and binoculars if you have them — even basic 7×50 binoculars reveal dramatically more than the naked eye.
For cabin stargazing, the hot tub is your observatory. Give your eyes 20–30 minutes to fully dark-adapt after turning off all cabin lights. A free app like Stellarium or Sky Map on your phone can help identify constellations — just enable the red-screen night mode to preserve your night vision.
Seasonal Stargazing Guide
Summer offers the Milky Way directly overhead, the Perseid meteor shower in August, and warm enough conditions for comfortable extended viewing. The trade-off is shorter darkness — true dark does not arrive until after 10 PM in June and July.
Fall brings earlier darkness, clearer air as humidity drops, and the Andromeda Galaxy rising into prime viewing position. The Orionid meteor shower in late October provides a bonus for fall foliage visitors.
Winter delivers the best seeing conditions — cold, dry air produces the sharpest telescopic views. Orion dominates the southern sky. The Geminid meteor shower in mid-December is often the year's best. The trade-off: it is cold. Dress for it or observe from your hot tub.
Spring features galaxy season — the Virgo and Leo galaxy clusters are optimally positioned for deep-sky observation. Guided programs resume in early March.
