We’re well on ‘The Savannah Way’ now!

We feel as though we’ve left the “standard” East coast cities and now making our way into the Outback. The route we’re taking from Cairns to Broome is known as ‘The Savannah Way’ as it is covered by savannah like grasses.


The Savannah Way follows this route from Cairns:

Today we visited the Undara Lava Tubes which is just WSW of Normanton where the white spot is.


The Undara Lava Tubes were formed some 190,000 years ago when a major volcano in the McBride volcanic province erupted, its molten lava flowing down a dry river bed. As the top layer quickly cooled and crusted, the fiery magma below continued to flow through the tubes taking it further and further from the volcano.  As the eruption slowed and then stopped, the lava drained out of the tubes leaving a series of long, hollow tunnels.
Ancient roof collapses created deep, dark and moist depressions where fertile pockets of rainforest can now be seen.
Rainforest plants and animals thrive in this environment; each tube offers a rare insight into this unusual geological wonder.
The word Undara means ‘a long way’ in Aboriginal language. One of the lava flows from Undara extends over 160 kilometres (or 100 miles). This makes it one of the longest lava flows from a single volcano on our planet in modern geological time. The original tube formed by the flow extended for approximately 100 kilometres, and several sections are accessible.
It has been estimated that during the eruption, the Undara volcano spewed forth 23 cubic kilometres of lava covering 1,550 square kilometres. So far, 68 separate sections of cave have been identified from over 300 lava tube roof collapses.”  copied from http://undara.com.au/lava-tubes/

We went on a half day tunnel tour and what we saw was simply incredible.


Once again, Mother Nature has shown us how incredible she can be.


Stay tuned for the photos…
