Tweed Volcano

Tweed Volcano is an extinct volcanic formation in northeastern New South Wales that spans a large area and encompasses several notable landmarks including Mount Warning and the Border Ranges. The region displays varied terrain with plateaus and steep slopes that resulted from millions of years of volcanic activity.

The volcano formed as the Australian continent drifted over an underground hotspot and remained active over a long period before becoming dormant approximately 20 million years ago. Since then, erosion and weathering have significantly altered the original structure.

The surrounding Gondwana Rainforests contain over 500 waterfalls and provide habitat for native plants including Doryanthes palmeri and Dendrobium speciosum.

The area is crisscrossed with hiking trails of varying difficulty that make different parts of the volcanic formation accessible. Visitors should expect variable weather and bring sturdy footwear and plenty of water.

The eastern side displays one of the largest erosion calderas in the Southern Hemisphere with spectacular cliffs and deep gorges. This distinctive erosional landscape developed through millions of years of water and wind erosion after the volcano cooled.
