Abandoned Caves

Some of the largest and longest lava tubes on Zihæt, these abandoned caves are located on the southern end of the Froúrio Range.


The lava tubes formed immense tunnels and caves, one of which is approximately 1.3 kilometers long, 11 meters high and 20 meters wide.

Localized Phenomena

The caverns have been also been called "bad air caves" due to high levels of poisonous gas which can collect in the winter months. While the levels are often sufficiently low for plantation slaves to ride out the summer and late fall storms, they rise in the colder air of the winter making the caverns nearly uninhabitable.

Fauna & Flora

The caverns are inhabited by all manner of reptile and flying mammal. Snakes, bats and more dangerous animals have been known to lair in the areas nearest the entrances and prey upon the local forest wildlife at night. Deep within the caves, more dangerous creatures able to tolerate the poor air can be found.   Within the caves, fungus and plant life is minimal due to the poor growing conditions and toxic air.

Natural Resources

The caverns are a layered with rich basalt. Other mineral deposits have been found, but are often found deeper into the tunnels where the air is poor.


The lava tubes were thought to be formed by immense volcanic activity which occurred hundreds of millennia ago. The lava that poured through these tubes formed the fertile plains of what is now the Sfentámi forest.
