Exploring caves isn’t something everyone does on their Iceland trip, but venturing into Vatnshellir Lava Cave offers a glimpse into a volcanic world that’s both fascinating and surprisingly accessible. This 45-minute guided adventure takes you underground into an 8000-year-old lava tube, revealing the natural artistry of melted rock and the story of Iceland’s volcanic activity.

The guide, part of Summit Adventure Guides, leads you through this spectacular volcanic tunnel that’s been shaping Iceland’s landscape for millennia. The tour’s duration—just 45 minutes—makes it a perfect quick adventure, yet it’s packed with enough sights and stories to satisfy your curiosity.
The starting point is the designated parking area at Vatnshellir Cave, from where you’ll meet your guide and get geared up. It’s advised to wear warm clothing and sturdy shoes—hiking boots are recommended because of the uneven terrain—and gloves are suggested for comfort and safety. The cave maintains a near-constant temperature just above freezing, so dressing warmly is a must regardless of the season.
The Itinerary in Detail
The tour begins at the cave entrance, where your guide explains the geological history of Vatnshellir, which dates back thousands of years. You’ll then descend into the underground world, passing through two spiral staircases that wind through the volcanic rock. These staircases are part of what makes the tour accessible yet engaging—they challenge your balance a bit, but you won’t need any specialized climbing skills.
Inside, you’ll encounter lava formations with remarkable textures and colors, shaped by flowing lava and cooling patterns. The guide shares insights about how lava tubes form and what makes Iceland uniquely volcanic. Several reviewers have mentioned that the explanations are clear and informative—even if one found parts of it “a bit boring,” most appreciated the detailed descriptions and the chance to see something truly rare.
Exploring the Lava Formations
The lava tube’s interior showcases a variety of features: smooth walls, stalactite-like formations, and pools of cooled lava. The visual contrast between different lava flows makes the environment visually captivating. Some parts are darker, while others display surprising hues, adding to the cave’s mystique.
The highlight for many visitors is imagining the volcanic eruption that created this tunnel over 8,000 years ago. The guide’s commentary helps you understand the process, making the experience not just visual but educational.
The Practical Aspects
The tour is designed to be accessible to most physically capable visitors, but it’s essential to note the walking on uneven surfaces and the two spiral staircases. Reviewers have pointed out that this isn’t suitable for very young children or people with limited mobility. However, for those comfortable with walking and small ascents, the experience is manageable.
The cave’s lighting is limited, so your helmet-mounted flashlight becomes your best friend. This limited lighting adds to the thrill and authenticity—you’re exploring a natural formation not extensively lit like a tourist attraction.
More Great Thing To Do NearbyThe Value for the Price
At $43 per person, the tour offers a unique window into Iceland’s volcanic landscape—for many, it’s a fair price considering the rarity of the experience. The inclusion of helmets and flashlights means you’re ready to explore without extra costs, and the small-group setting ensures personalized attention.
While some reviews mention that the explanations could be more engaging, most agree it’s a solid, interesting experience. The tour is especially good for geology buffs or travelers seeking a quick but meaningful underground adventure.
Who Is This Tour Best For?

This lava cave tour caters well to curious travelers eager to see Iceland’s volcanic history firsthand without committing to a full-day adventure. It’s perfect if you’re interested in geology, caves, or volcanic landscapes, and don’t mind a physically active experience on uneven terrain.

However, if you prefer flat, well-lit environments or have mobility issues, this might not be the ideal choice. Given the limited duration, it’s a good add-on if you’re already exploring the Snæfellsnes region and want a taste of Iceland’s underground volcanic world.
