Descend into Jules Verne’s Underground World
Step into the pages of “Journey to the Center of the Earth” as you explore Vatnshellir Cave, an 8,000-year-old lava tube that inspired Jules Verne’s classic novel. Located beneath the mystical Snæfellsjökull glacier on the Snæfellsnes Peninsula, this underground adventure offers a fascinating glimpse into Iceland’s volcanic past.
A Literary and Geological Marvel
Vatnshellir Cave gained fame as the starting point for the underground journey in Jules Verne’s 1864 novel. Formed when lava flowed from Snæfellsjökull volcano toward the sea roughly 8,000 years ago, the outer layer cooled while the molten interior kept flowing, eventually draining and leaving behind this spectacular passage. Today, a spiral staircase takes you 35 meters down into the earth where your headlamp reveals dramatic rock formations, smooth pahoehoe lava, and chamber after chamber of volcanic textures and colors.
What You’ll Experience Underground
Your expert guide leads you through distinct chambers and passages, each with unique characteristics. Along the way, you’ll learn how Iceland’s volcanic systems create lava tubes and discover the cultural connection between this cave and one of literature’s greatest adventure stories. The well-maintained pathway makes this accessible to most visitors without requiring specialized skills.
A Perfect Snæfellsnes Addition
Located beneath the glacier-capped Snæfellsjökull volcano, the cave pairs perfectly with other Snæfellsnes Peninsula attractions. If you want to include this cave visit in a full day tour, check out our Snæfellsnes peninsula small group tour and lava cave.
