Each Lava Show begins with a short introductory film on Iceland’s shifting tectonic plates and volcanic timeline, after which lava masters demonstrate how lava is formed and behaves in natural environment.

People swear by just how magnificent Raufarhólshellir is and it’s easy to see why. It’s one of Iceland’s longest and best-known lava tubes located just 30 minutes from Reykjavík. It’s a perfect off-beat adventure for anyone looking to experience Iceland beyond the usual sights.

Each Lava Show begins with a short introductory film on Iceland’s shifting tectonic plates and volcanic timeline, after which lava masters demonstrate how lava is formed and behaves in natural environment.

Real molten lava is created by superheating Icelandic basalt rock to over 1,100°C in a custom-built furnace. During the show, lava masters carefully release and guide the glowing flow onto the stage, allowing people to watch it spread, crackle, and cool.

As the lava spreads, it starts thickening, cracking, and forming rippled surfaces. This mirrors how real lava behaves in nature, where temperature and flow speed determine whether it hardens into smooth sheets, jagged crusts, or layered rock formations.

As part of the premium experience, you get a small piece of real cooled lava formed during the show.

On the lava tunnel tour from Reykjavík, you’ll walk through vast natural caverns inside Raufarhólshellir, carved by fast-flowing magma thousands of years ago. As the outer lava cooled and drained away, it left behind hollow chambers with high ceilings, sculpted walls, and dramatic underground spaces shaped entirely by volcanic force.

On the one hour walking tour, the guide will explain how lava tubes form, why rock layers vary in color and texture, and what these formations reveal about eruption speed and temperature.

Inside Raufarhólshellir, you can see hardened flow lines, lava shelves, and smooth rock “rivers” frozen in place. It has even left clear, physical traces of how magma actually moved underground during the eruption.

Best time for lava experiences in Iceland: There’s really no wrong time to experience Iceland’s lava attractions. The Lava Shows in Reykjavík and Vík run year-round and fit seamlessly into any season(November–March). Lava tunnels are especially rewarding outside peak winter, when conditions make underground exploration more comfortable and unhurried.


Yes. The Lava Show uses real Icelandic basalt from previous eruptions, reheated to molten temperatures in industrial furnaces.
Dont worry, the temperature you feel is comparable to standing near a campfire or an open oven for a moment. While you’ll definitely notice a wave of heat when the molten lava is poured, it’s brief, controlled, and part of the experience.
The standard Lava Show runs for approximately 50 minutes, while the premium experience with a backstage tour lasts about 75 minutes.
Photography is usually allowed, but flash and tripods may be restricted for safety reasons.
Definitely. The Lava Show lets you experience real molten lava up close without hiking or depending on volcanic activity.
Iceland sits on the Mid-Atlantic Ridge, where two tectonic plates pull apart. This constant movement allows magma to rise frequently, shaping the island through repeated eruptions over millions of years.
The tunnel is spacious in most sections, but it is enclosed and dimly lit.
Dress warmly and wear sturdy, closed-toe shoes. The tunnel stays cool year-round, and the ground can be uneven. Helmets and headlamps are provided.
The walking tour typically lasts around 60 minutes, including time inside the tunnel and explanations from your guide.
Yes, photography is allowed in both experiences. Just be mindful of safety instructions and lighting conditions especially in the tunnel, where flash may be limited.
As lava cools, it forms repeating patterns influenced by temperature, flow speed, and chemistry. These patterns can resemble fractals, meaning similar shapes appear at different scales.
Choose the Lava Show if you want a low-key experience with dramatic visuals. Go for the lava tunnel if you want a hands-on, outdoor encounter with Iceland’s raw geology.
