A few of the trails are but not all, make sure you ask someone if you're not sure which ones to take. They will give you a map at the gate.
The Mashburn Family Discovery Trail is .72 miles and has an easy designation. It is described as "This level trail is designed for persons of all abilities." Although some of the other trails are rated as easy, they are not Ada accessible.
There are paved areas that are near woods and a bird blind. If you are seeking a place to be out in nature, with mature trees/woods, as well as many nice plantings, such as thousands of now-naturalized spring bulbs, you will certainly enjoy the Cincinnati Nature Center. There are exhibits, a bird watching area, a library and gift shop in the main building.
There is one paved ADA trail which is about a half a mile long. There is one rather level trail that goes down to the lake but it is gravel, which may or may not be suitable. The main building is also accessible.
I am sorry but I don't know the answer. I was visiting from out of state and was there for a wedding. You might want to call them to find out.
