There is limited handicap accessibility. You would get to see the Ohio State Corrections museum, the wardens dinning room, and the museum store. Then there's access to both cell blocks, solitary confinement, the bull pin, both shower rooms, and the central guard room. But it is not heated in the winter, so prepare for very cold weather or wait til about May when it finally warms up a bit.
Some but not all
Not really, as soon as you start the tour it takes you up a flight of steps to the very top floor
