The Forrestania Plots Camping Area is a great place to camp for the night on your trip across the nullarbor with Plenty of self-contained bush camping spots with a few fireplaces.
Note: The ground is quite hard to drive tent pegs into.
There is an old building that was known as McDawell House, in recognition of the late Tom McDawell who was the main driving force of the Forrestania Plots. This place has an interesting history, and there is a plaque erected there explaining it.
