A larger person would have to turn side ways at a couple spots on the natural wonder tour. Depending on how large they may rub against the sides
I'm large and heavy, I had to turn once to the side. If you are taller 5han 5'3" you will need to duck in a few places
Yes it will be tight in spots but do able
Was a few heavy folks on our tour the last 60 stairs were ruff on all of us. Lol but they fit fine.
I'm 6'+ and 350+ and I had a little trouble. Hardest part might be the 60 steps back to the surface.
You would still be able to enjoy the tour. You would just need to adjust how you go through the narrow pathways.
Challenge in some areas, but you should be fine
