I'm wondering if anyone has recently? been able to purchase tickets on line for the caves. I've gone to the official website a few times over the past couple of weeks and when I try to purchase tickets it doesn't allow me to select the number of tickets....system just blanks out number of tickets so I can't get past that point. Thanks for your help.

It is a little while since we visited but we just turned up and bought at the ticket window.

Maybe try deleting your cookies and/or internet history?

Have you tried emailing? or even calling?
The caves are intriguing and IMO well worth seeing. Enjoy!

Thanks everyone.
