cuyahoga valley national park

Have you looked through the website?
Cuyahoga Natl Prk
April 8th is set for eclipse through Ohio.

We visited on our way home, wasn’t impressed and kept on driving. The newest NP in WV, New River Gorge is interesting.

I live nearby there. The weather is normally chilly that time of year, sometimes snowy. Many Cleveland Indians April home games get postponed.

Brandywine Falls is the best attraction there in my opinion, should be churning pretty well that time of year.

I'd suggest staying at West Branch State Park, or Atwood Lake (Atwood Lake has newer FHU if needed, but pricey)https://atwoodpark.mwcd.org/

You won't need 3 days there to take the park in. Cleveland (and Akron & Canton) gets a bad rap, but its truly a great region with museums, wineries, & breweries.
Holmes County isn't too far from Cuyahoga Valley NP, has a great Amish community with cool restaurants & markets. So if you're into that kind of stuff, 3 days may not be enough.

We visited CNP in 2022. The park is beautiful considering the otherwise unassuming landscape of the area. Note it is basically surrounded by city, so it makes for an interesting experience. We enjoyed the big hitters including the Ledges, Brandywine Falls, Bridal Veil Falls, Blue Hen Falls, Tinkers Creek Gorge, and both visitor centers. That was a full day and didn't allow us to ride the Scenic Railroad, hike as much as we wanted, or to get out on bikes or kayaks. Two full days or three relaxed days would be best if you had the time.
