As stated in the other post. true no one should use a scooter in there for cave conservation, but a scooter could be brought in from there to use it in the main tunnel..
I do doubt that they are same distance. I am very certain that it takes about 20 min from the Jump to Gran at "normal" pace swimming (having that done so many times) while it is only 10 max 15 min or so to Ho Tul I think as I remember.. Did that passage less often because when I wanted to go to to cuzan Nah area I take the direct route from Gran and when I stay on main I head towards Paso de Lagarto
You are correct about the distance, Ho Tul is a lot closer. It’s not even as far away as in your recollection. The distance to the jump is perhaps 80 meters or so. It took four minutes to swim.
