Red Cliffs - These fantastic red coastal cliffs are found about 1km north of saltwater creek in Ben Boyd National Park. The cliffs are made of a red siltstone. As the name suggests, this rock is made from deposited silt, making it much finer grain than sandstone. The red silt came from nearby volcanic eruptions long ago, and is clearly different from the other brown siltstone and sandstone in the region. The cliff is unfenced and provides views out to sea and into a few surrounding bays.
