If you are driving from Woomera to Alice Springs you'll pass some salt lakes. You can stop on one of the view points. We stopped at the last one on the right. We walked up the salt lake. Not too far though. Just read the picture and you'll understand. Woomera is also a big military practise ground. It's illegal to get off the Stuart highway in the neighbourhood of Woomera.
Woomera is a very depressing place. This is where Australia puts their illegal immigrants. You can't get to this site because the cops will intervene. Another thing woomera is known for is it's rocketlaunches. There's a small park with many old rockets and planes. It's possible to make a silly travel picture over there.
If you are driving on the Stuart highway it's a good place to make a stop.
Missile Park and the visitor's centre (formerly a recreation centre for US army personnel) are Woomera's main attractions, worth a stopoff if you're passing through Woomera.
