The Nimbin Rocks are volcanic extrusions of Rhyolite left over from the Mount Warning Tweed Volcano that erupted around 20 million years ago. As part of an eroded dyke of the volcano, Nimbin Rocks are located just outside the present day caldera wall about 20 kilometres from Mount Warning and three kilometres from Nimbin Village. They are an extremely significant cultural site to the local Bundjalung tribe who believe the rocks were home to the Nmbngee, or Clever Men. They were also the initiation grounds for young boys.
