Step into the incredible, cavernous depths of Thurston Lava Tube, a remarkable geological formation within Hawaiʻi Volcanoes National Park. This large lava cave was created centuries ago when a river of molten lava flowed through the area, its outer layers cooling and solidifying while the hot lava drained away. Walk through this natural tunnel, marveling at the smooth, sculpted walls and the lush rainforest vegetation that thrives at its entrance and exit. The tube offers a unique perspective on volcanic processes and the fascinating underground world they create. Keep an eye out for native Hawaiian birds that sometimes take shelter within its cool interior.
