Just returned from a trip there mainly diving to see the whale sharks etc but did a land tour (tame after the diving). Plenty of lava tubes out there and managed to get a look at a couple. I see that an international symposium is being held there next year. As a matter of interest is anybody going out there from the UK for it?  If so and they want any up to date info or advice I would be glad to offer it (general not speleological).

I'm hoping to go and would be interested in any insider info, Pete.

Nick.

Not a lot to share but will meet up at HE if you are going.
