It was a 8:00 am start for the lava tube tour, so it was a quick breakfast and off to the meeting point. With the temperature at 10C when we woke this morning it was jeans on for the first time.

Undara National Park is closed to the public, only authorised tour operators are allowed to take people in, this apparently is because access to the lava tubes must be monitored because the CO₂ gas levels can be high enough to cause people to pass out.

The main lava tube in the park is about 100 kms in length broken into many pieces by roof collapses and lava direction flow changes. We chose the easier of the tours that did not require any rock climbing. The caverns were quite impressive, some higher than others due to part of the roof falling in.

After the tour we went to Kalkani Crater where there is a 2.6 km walk around the rim of the old crater. It was the first time Jacky & I had walked around the rim of a volcano. From there it was back to the resort where Jacky generously paid for our lunch at the bistro. When they were setting up the resort the owner had the opportunity to purchase a lot of old Queensland railway carriages and he restored them and used them in resort from accommodation, dinning and information centres, there would be nearly 40 carriages on the property.

The evening was finished off with a trivia quiz around the campfire.
