Caves/Lava Tubes

[Cindy Blankenship]

I don't know if I'm replying in the correct place since this thread is from last year but here goes..Akoni wrote about the Lava Falls Tour at Kazumuru Cave. Does anyone have a contact number for this?
Also, my son and I hiked the lave tube next to Thurston and are looking for something a bit more challenging (well he is anyway) and with more to see, bigger that. Sounds like the guy you mentioned gives a hoot about the environment :-)

Well, if you all get this...
Mahalo!
