A volcano the Ewamian people would later call Undara poured out one of the largest lava flows from a single vent that the planet has produced in the past few million years. The molten rock surged down ancient riverbeds, and where the surface cooled and crusted over while the liquid interior kept racing on, it left something extraordinary behind: hollow stone tunnels, kilometres long, running like veins beneath the savanna. The name fits. Undara means 'a long way' in the Ewamian language, and the lava travelled it - the longest flow stretching roughly 160 kilometres from where it began.

When lava floods a channel, its outer skin meets the air and hardens into a roof while the molten core beneath stays hot and mobile. When the eruption finally wanes, that liquid drains away downhill and keeps going, leaving the crusted shell sta...

It is the showpiece of the McBride Basalt Province, a roughly 5,500-square-kilometre region pocked with 164 identified eruption centres - volcanoes, vents and cones, each a place where the earth once opened. From the rim of Kalkani Crater, one of the ...

Where the ceiling has fallen in, sunlight and trapped moisture turn the depressions into pockets of dense green vine thicket, lush islands of rainforest with deep affinities to the ancient flora of Gondwana, su...

European settlers moved in during the 1860s, running cattle across the basalt plains; the Collins family, who settled the area in 1862, eventually built the visitor operation that became the Undara Experi...
