Exploring the Lofthellir Ice Cave Inside a Lava Tunnel: A Honest Look

If you’re considering adding an adventurous caving experience to your Iceland trip, the Ice Cave Lofthellir exploration is one to seriously think about. This tour takes you deep into a permafrost ice cave nestled inside a magma tunnel — a spectacle of natural Icelandic geology that’s both fascinating and a little challenging. While it’s not a casual stroll, it offers a rare glimpse into a frozen world that’s unlike anything else.
What we really appreciate about this tour is the personalized attention it offers. With a maximum of just 10 travelers, it feels more like an exclusive expedition, guided by knowledgeable locals who clearly love sharing their homeland’s secrets. Plus, the entry fees to Lofthellir are included, which simplifies planning and adds value. That said, it’s important to note that this experience demands a moderate level of physical fitness and a willingness to squeeze through tight spaces and navigate icy surfaces.
In terms of potential drawbacks, the tour involves navigating narrow, confined spaces, which could be uncomfortable for those with claustrophobia or mobility issues. As one reviewer pointed out, “this tour requires squeezing through a couple of tight spaces and sliding on ice.” If you’re physically fit and enjoy a bit of adventure, though, it’s an experience that’s well worth considering. This tour is particularly suited for active travelers who love geology, exploration, and don’t mind getting a little dirty or cold.
This isn’t a tour for everyone, but if you’re craving a unique, hands-on adventure and are okay with some physically demanding moments, it’s a chance to see one of Iceland’s most astonishing natural phenomena. Now, let’s take a closer look at what makes this experience special—and what to keep in mind before booking.

An In-Depth Look at the Lofthellir Ice Cave Tour

What is the Lofthellir Ice Cave Exploration?
This tour offers a journey into a permafrost ice cave located inside a lava tunnel — a geological marvel created by volcanic activity. While most lava tubes are dry and dark, Lofthellir is unique because it’s filled with ice formations that have persisted within the cooling lava tunnel.
What sets this experience apart is the chance to see this frozen world up close. You’ll be exploring a frozen cavern, with the opportunity to marvel at the natural ice sculptures, formations, and the stark contrast of ice within volcanic rock. This makes for a visually stunning and scientifically intriguing journey into Iceland’s volcanic history.
How the Tour Is Structured
The tour begins in Reykjahlíð, where you’ll meet your guide and hop into a rugged offroad vehicle for the drive through the volcanic landscape of Lúdentartborgir — the volcanic area responsible for the creation of Mývatn. This off-road drive alone is an adventure, offering scenic views of Iceland’s volcanic outback.
Once at the entrance, you’ll start exploring the Lofthellir lava tunnel, which takes roughly 2 hours. The exploration is divided into two main sections: first, navigating through narrow spaces near the entrance — which involves crawling, sliding, and squeezing — and then stepping into the larger, awe-inspiring open sections of the cave where the ice formations can be fully appreciated.
What to Expect During the Cave Exploration
According to reviews, the initial part involves crawling through tight spaces, which can be daunting for those with claustrophobia or mobility limitations. The experience requires you to squeeze through narrow passages and slide on ice, which is why good physical fitness is recommended.
Once inside the cave, you’ll be treated to spectacular views of ice stalactites, stalagmites, and frozen waterfalls. The guides, who are very knowledgeable, will share insights about the cave’s geology and Icelandic volcanic activity, adding context to what you’re seeing.
Equipment and Safety
All safety gear is provided, including helmets, headlamps, and studded boots. The studded boots are essential for walking on icy surfaces, enhancing grip and safety. Travelers are advised to wear waterproof gloves, shells, and wool socks — as some reviewers noted — to stay warm and comfortable.
The Experience’s Highlights
- The contrast of ice and volcanic rock creates a surreal landscape.
- The guides’ local knowledge and friendly approach enhance the experience.
- The small group size means more personalized attention and better interaction.
- The entry fee is included, so no surprises or extra costs.
Who Will Love It — and Who Should Approach With Caution?
This tour is ideal for active, curious travelers who are not afraid of getting a little dirty or cold. It’s a fantastic choice if you’re interested in geology, natural phenomena, or adventure. One reviewer summed it up: “Very unique experience. Our guide was very knowledgeable,” which hints at how valuable the guided aspect is.
However, it’s less suited for those with mobility issues or claustrophobia. The tight squeeze through narrow spaces can be uncomfortable or impossible for some, so be honest with yourself about your comfort level.
Price and Overall Value
At around $405.55 per person, this tour isn’t cheap, but it provides entry into a rare natural environment that’s tough to access independently. The inclusion of all equipment and entry fees makes it easier to assess the true value. Many find that the exclusive experience, guided insights, and the adventure itself justify the cost.
Final Thoughts: Is It Worth It?

For adventure lovers and geology enthusiasts, this Lofthellir ice cave exploration is a must-do. The chance to see inside a lava tunnel filled with ice is a rare opportunity. The guides’ expertise and small group size mean you’ll get a more personalized, engaging experience, making it well worth considering if you’re comfortable with the physical demands.
That said, for travelers who are not physically active or prefer more relaxed tours, this might be a bit intense. Be prepared for tight spaces, cold conditions, and some physical effort. But if you’re up for it, the memories of this icy adventure will definitely stick with you long after your trip ends.
In the end, this tour is a blend of adventure, geology, and natural beauty. It offers a genuine, hands-on look at Iceland’s volcanic past and thriving ice formations. Perfect for those who want a little more than the typical sightseeing—something truly unique and memorable.
