Reykjavik: Silfra Snorkeling & Lava Tunnel Adventure Combo

Reykjavik: Silfra Snorkeling & Lava Tunnel Adventure Combo offers a chance to explore the volcanic heart of Iceland in one full day. For $209 per person, you’ll visit the surreal lava tunnels near Raufarholshellir, then glide through the crystal-clear waters of Silfra, floating between two tectonic plates at Þingvellir National Park. Guided by friendly and professional guides, this tour is a mix of adventure, geology, and breathtaking scenery.

What we love about this experience is how it combines physical activity with stunning natural beauty. First, the lava caving offers a tactile sense of Iceland’s volcanic past, with intricate rock formations and a sense of adventure in confined spaces. Then snorkeling in Silfra transports you to an otherworldly blue landscape, where water clarity and vibrant hues make you feel like you’re floating in a dream. Plus, the inclusion of free underwater photos and a warm post-snorkel cocoa means you’ll have tangible memories without additional costs.

One potential consideration is the cold water temperature, which is notable since Iceland’s waters hover just above 0°C. While suits and gear keep you warm, some might find the initial shock of submersion a challenge. Also, the tour is not suitable for children under 12, pregnant women, or those with certain medical conditions, so it’s best suited for confident swimmers and adventure seekers.

An In-Depth Look at the Tour Experience

The Lava Tunnel: A Geological Journey

Your adventure begins with a visit to the Raufarholshellir Lava Tunnel, a captivating underground labyrinth formed by volcanic activity. Here, you get a firsthand look at Iceland’s volcanic past through vibrant rock formations, dark tunnels, and twisting passages. The tour guide — often described as friendly, funny, and full of interesting facts — will lead you through the tunnel, explaining the geological processes that shaped this underground world.

Many reviews highlight how engaging guides make the experience more than just a walk through a cave. For example, one traveler noted that their guide “offered to take photos and recommended spots for pictures,” adding a memorable personal touch. The cave is not as colorful as limestone caves, but the sheer size and formations make it worth exploring. Some reviewers appreciated the opportunity to explore at their own pace after the guided part, which adds a sense of adventure and discovery.

A key aspect is the safety and equipment — you’ll be provided with caving gear, including helmets and headlamps, to navigate the darker sections comfortably. The experience lasts about 30-40 minutes, and many say it’s “truly an adventure” that feels like stepping into a volcanic ghost story.

Transition to the Silfra Fissure

After the lava tunnel, you’ll have some time to refuel before heading to the next highlight: Snorkeling in Silfra. The drive from the lava cave to Þingvellir National Park is scenic, showcasing Iceland’s expansive landscapes and rugged beauty. Arriving at Silfra, you’ll notice the remarkable clarity of the water — often described as the clearest on Earth.

Snorkeling in Silfra: An Otherworldly Experience

Guided by certified PADI instructors, you’ll be fitted with all necessary gear, including wetsuits, drysuits, masks, and fins. The water temperature hovers around 2°C, but thanks to the quality gear, most find it surprisingly comfortable, especially with the added warmth of the suit. The experience involves floating effortlessly in the fissure, with a gentle current guiding you through a landscape of shimmering blues and greens.

Many reviews praise the guides for their patience and safety focus. One traveler said, “John was brilliant and made sure everyone was okay,” which is reassuring given the cold water and the need to stay calm and buoyant. The underwater photos taken by guides are a hit among participants, capturing the surreal landscape of the split between North American and Eurasian plates.

You’ll stay in the water for approximately 40 minutes. The experience of “floating between two continents,” with the vibrant colors and the silence underwater, tends to be a highlight that stays with travelers long after.
