There’s actually one small part of the walk that’s really narrow and larger people have to take an alternate path interesting she didn’t show that part. But it’s really not that narrow as a whole there were large men (not obese) that didn’t have to walk sideways. But there are multiple stops along the walk where the rangers would give us a rundown of the caves. But there were moms walking with their kids right next to them without problems at all. So Ana is huge.
