Glow Boats and Stargazing Return to Miami Whitewater Forest
Great Parks of Hamilton County is turning the lake at Miami Whitewater Forest Harbor into a nighttime attraction again this August. Spark in the Dark runs 8 to 11 p.m. Friday, Aug. 7, and Saturday, Aug. 8, at the Harbor, 9001 Mt. Hope Road in Harrison. The event pairs glow-lit boat rentals with a night hike and stargazing led by the Cincinnati Astronomical Society, and pre-registration is not required.
For Hamilton County families used to the harbor as a daytime fishing and paddling spot, the appeal here is the after-dark version: the same 85-acre lake, but with illuminated boats on the water and telescopes set up on shore.
What’s Happening on the Water and the Trail
Guests can rent glow-lit boats to paddle the lake after sunset, with refreshments available for purchase at the snack bar. Great Parks describes the lineup as glowing boats on the water, a night hike focused on nocturnal wildlife such as moths, bats and bugs, and telescope viewing with the Cincinnati Astronomical Society. Boat rentals at the Harbor normally start around $16 for a rowboat or pedal boat, with kayaks, paddleboards, motorboats and mini-pontoon boats also available.
Good to Know
- A valid Motor Vehicle Permit is required to enter any Great Parks property by car, including Miami Whitewater Forest.
- Night fishing is not permitted during the event.
- Outside alcohol is not allowed. Any alcoholic beverages consumed on site must be purchased from the snack bar, under Great Parks’ boat rental guidelines.
- The Harbor’s posted hours for early August run 9 a.m. to 8 p.m., so the 8 to 11 p.m. event window is an extended, special-event exception to normal boathouse hours.
