A Closer Look at the Vatnshellir Lava Cave Tour

If you’re planning to add this experience to your Iceland itinerary, it’s helpful to understand what to expect from start to finish. The tour is offered daily, lasting about 45 minutes, which makes it manageable even on a busy schedule. You’ll meet at the parking area at Vatnshellir Cave, where your guide will gear you up with a helmet and flashlight—standard safety gear that makes a huge difference in the underground environment.
The Itinerary and Cave Exploration
The main highlight is the guided walk through Vatnshellir itself. This lava tube has been shaped over thousands of years, revealing a landscape of volcanic formations, colors, and textures. The guide will take you through the tube, pointing out features that illustrate Iceland’s volcanic history. It’s like stepping into a natural art gallery carved by volcanic activity.
During the tour, you’ll encounter two spiral staircases leading down into the cave. These are the only points where support and vertical movement are involved, and they’re an interesting part of the experience. While the route is straightforward, you’ll want to be comfortable walking unsupported over uneven ground and navigating the staircases. The tour isn’t suitable for those who struggle with stairs or limited mobility, and you should be prepared for low lighting conditions.
What to Wear and Bring
Because the temperature inside the cave stays just above freezing year-round, dressing warmly is essential. Think layers—you’ll want thermal underlayers, a warm jacket, and gloves for comfort. Hiking shoes or sturdy sneakers are recommended, as the terrain is uneven. High heels, flip-flops, or flat-bottom shoes are not permitted for safety reasons.
The guide provides helmets and flashlights, but you should bring your own extra warmth if you tend to get cold easily. Gloves are also recommended for safety and comfort, especially when touching cave surfaces or navigating the staircases.
