No. There is 1 hour of walking and you have to walk 64 steps down and back up.
Actually it would be completely accessible now! There is not a single stair to go down they have made ramps with handrails everywhere! The new entrance is only been open for 2 weeks! That is June 2019.
As of November 2018, it is not wheelchair accessible. I see the potential challenges being the fact that it's a natural geological formation (a cave and an expansive one at that) which presents major logistic and design challenges. That said, they may be to eventually get something. The car museum, garden maze and history display are wheelchair accessible.
They are currently making the cavern handicapped accessible. This may take some time to complete
While there are no stairs to enter the caverns, it is still a mile and a quarter in the cavern with inclines and declines. It is not handicap accessible but it is completely paved with no stairs
No, walking a lot up and down steps and the walk takes more than an hour.
