Inside, you'll witness stunning geological formations including vibrant, rainbow-colored walls (red, orange, yellow) caused by mineral oxidation, intricate lava stalactites, and naturally sculpted lava falls. You can also observe ropy pahoehoe textures and flow lines on the walls, providing a visual record of ancient lava flows. In winter, spectacular ice formations add another layer of beauty.
The temperature inside the tunnel remains consistently around 5°C (41°F) year-round. Therefore, it's crucial to dress warmly in layers, even in summer. A warm jacket, hat, gloves, and sturdy, closed-toe shoes with good grip are highly recommended. Helmets and flashlights are typically provided by the tour operators.
