tickets are always FREE, except for special exhibits. this is one of the best art museums in the country, and totally worth a visit.
newly renovated (and where alli used to work!) the museum has a free visitor hall, but tickets are required to enter the exhibits. they have a great outdoor ohio wildlife experience where you can see native ohio animals, like coyotes and lance the porcupine.
specifically, the fort hill stairs and trail at the nature center. it gets busy in the fall due to the leaves, but it's a beautiful park and area to check out very close to cleveland.
what more is there to say, go check out this awesome place in downtown cleveland. (it's super easy to get an uber / lyft to)
great food market to walk around. nice spot to get baked goods, spices, fresh produce if you're cooking any meals while you're in cleveland, or to grab a coffee and walk around. there is parking behind the market, with a couple entrances.
