Cuyahoga Valley NP - Terra Vista Natural Study Area
This area felt very remote, with a lot of wildlife (saw a turkey vulture eating the carcass of a some mammal and many other birds) and unkempt trails. After a gravel road to get to the top of the hill, the trails up top were generally mown grass, though they were extremely overgrown and often muddy. In one place, the path required trudgin through a slightly-higher-than-ankle-deep swamp. The area was very buggy. The scenery was nice, traveling alongside many wetlands. The trail only infrequently went into the forests, though they were always nearby. Would be worth trying again during a drier time of year.
Update: I ended up finding a tick on me and we found nine on Winnie. Avoid this trail during tick season.
With Winnie.
