It is! They have ramps from the parking lot to the building and from the building to the tram. The entire tour through the cave is on a tram. Only issue you might have is there is an area where the ceiling is low and you need to tuck your head. It might be an issue if you have trouble with that.
Yes it is
They have ramps every where. You will only have to step up into the tram.
From what I saw it is.
You only have to walk to the vehicle in which you ride through the caves.
