In this weeks episode we finally make it the fabulous Undara Lava Tubes after stopping in at Australia's smallest bar.
Come along as we tour this amazing geological wonder in far North Queensland.
We take a guided tour through some of the tubes and also visit the Kalkani volcanic crater nearby and finish with a wonderful dinner inside an old train carriage at the Undara village.
It was a great place to visit and get some geology nerd happening for Col.
