Never heard of Undara? No worries. But they have something there that´s worthwhile stopping for! Lavatubes. Geologists say the most beautiful and intact lavatubes in the world. During previous volcanic eruptions, a lot of the hot lava was channelled into riverbeds. While the surface of the flowing lava slowly cooled off, beneath the surface it remained hot and continued to flow – leaving behind a lavatube.
