Coober Pedy lies roughly 800km south of Alice Springs and about 800km north of Adelaide. If you're driving to & from Alice Springs to Adelaide, there is no way to avoid it. The town is surrounded by, well, nothing at all, above the ground that is. The main industry is opal mining. Opal was discovered there in 1915 and many return soldiers moved to town to mine it after World War 1.
Most of the town lies underground, which makes for a fairly deserted streetscape. It was the return soldiers who introduced the underground living, similar to the dougouts they lived in in the trenches of France. I had thought the underground houses were just to escape the heat! As I had never stayed in one of the underground hotels we took this return trip from Apollo Bay as the perfect opportunity. It was quite strange without natural light and silent, so silent. If you like to fall asleep in a quiet, dark room, The Desert Cave Hotel is the place for you.
We arrived early afternoon & set out on a little walking adventure, before having a beer at one of the pubs and an early pizza dinner. I love the fruit on the roof of John's Pizza Bar & Restaurant. Everyone from Alice Springs who has been to Coober Pedy says you have to have dinner at Tom & Mary's Greek Restaurant, but we think the pizza at John's is the bomb. After dinner it was a quick sink bath for Lulu and then early to bed for all of us to rest up for the last day of our three day trip home.
