Right, the Lava Tubes from yesterday. Whee!
So, after Mom and I hiked from the overflow parking lot for the Lava Tubes, parking there in error, to the main parking lot and the Lava Tube entrance (an easy 1km hike), we walked up a short distance, then down the paved switchbacks to the tube entrance. Which, by the way, totally looks like a cave you'd see in an Indiana Jones movie if said movies had handrails surrounding said caves. Oh, and signs pointing you where to go for the treasure:
There was a nice bit of stairs waiting for someone to wait at them, maybe hear a lecture on the lava tube formation (which, incidentally, was from a flow of lava having a slower flow cool on top of it and harden, as the now-buried flow kept moving), or record jungle bird sounds (which is what Mom and I did).
This is what the Lava Tube looks like inside of it:
It's like a damp cave, with lights. The tunnel wasn't very long, and we were through it in less than 5 minutes. It was neat to visit and learn about the formation of them. If you're at Volcano, do go walk through it.
