Must Sees in Cuyahoga Valley?

I may be going on a road trip to Chicago soon, and along the way we’re passing through Cuyahoga Valley, so why not go! I definitely want to do the Ledges trail and see Brandywine Falls, but please let me know if there is something else in the park that you highly recommend. Btw, this is not a “should I go?” post, so I don’t want to see anyone in the comments telling me not to go.
