Normal
I was there two years ago. I t hought it was great because you could see the ships passing through and the gates opening plus the machines that guide the ship through. I have not gone thru the canal on board but i feel i learned enough about it without doing that. The only difficulty in walking will be that there are stairs to climb to get up higher to see what is going on but you can still see a lot. I hope this helps. It really liked it as that is real history.
