Wollumbin (formally Mount Warning) is the remnant central plug of the Southern Hemisphere’s largest extinct shield volcano. Now eroded down to half its original height, the 1100 metre high Mount Warning offers a fantastic walk to the summit through rainforest communities. Given its name by Captain Cook, it was used as a warning to sailors of the dangerous Point Danger near Tweed Heads. It was named ‘Wollumbin’ meaning ‘cloud catcher’ by the Bundjalung people who inhabited the region before European settlement. Mount Warning was added to the World Heritage list in 1975. The Summit trail can be steep in parts and takes roughly five hours to climb. Toilets are only available at the start of the walk, suitable footwear should be worn, and temperature drops rapidly as you ascend, carry plenty of water, keep to the track and take all litter with you. There is a campsite nearby.
