Further up the track from the State Battery is the town¹s most interesting natural phenomenon -
London Bridge. It is the most spectacular and unusual of the
sandstone breakaways in the area and, in the early 1900s, was so large that carts could pass both across it and through it. The
sandstone in this area is estimated to be 350 million years old. The
bridge itself is nearly 800 metres long and at the centre is 10 metres high. It is now regarded as too dangerous to walk on.
