There were a few times it got tight. Ceiling height ranges between 30 feet down to 3 feet. The floor surface in some areas were as smooth as poured cement (obviously these areas had a chance to cool down slowly without disturbance) while most areas were not. What was amazing was how smooth the walls were.

Really cool video 👍🏻
Thank you Sophie. We're glad you liked it.
Looks like it got a little tight in there no? To think molten lava was running through there at one time !
Great vid.

Is there an opening in the other end of the tunnel?
There's no opening at the end. It's more like a 1 mile-long cave. It's an awesome thing to explore.
