A lava tube forms as liquid hot lava flows underground. The sides of the flow harden, leaving a tube behind. After the lava is done flowing, these tubes can be walked through like caves! The Thurston Tube is one of the bigger ones and runs nearly 600 feet long and 20 feet high!
Oh yeah, this is it. If Kilauea is actively erupting while you are visiting this stunning area, there is nowhere else you’d rather be. Depending on the year, you can take hikes out to the flow, watch through telescopes, or take helicopter tours of this breathtaking volcano. The best times to view this are early morning or after sunset. The contrast from the molten lava against the black sky and rocks will blow you away! Make sure to pack your Skyline Rolldown Backpack for this one, as you’ll need to bring a camera and a jacket for this hike, especially at night!
