SuperSaver Combo: Silfra Fissure Snorkeling + The Lava Tunnel

Exploring Iceland’s Hidden Wonders: Silfra Snorkeling & Lava Caves

If you’re dreaming of a day in South Iceland filled with surreal landscapes and adventure, the SuperSaver Combo: Silfra Fissure Snorkeling + The Lava Tunnel is one tour that promises to deliver. While we haven’t personally strapped into the wetsuit or crawled through lava tunnels, this experience comes highly recommended with a solid 4.5/5 rating from over 160 reviews, and a 92% recommendation rate.

What we love about this tour is how it combines two very different, yet equally mesmerizing outdoor adventures—one underwater and one underground—saving you time and money. The inclusion of all necessary gear, expert guides, and the chance to explore a UNESCO World Heritage Site adds incredible value.

A potential downside? It’s a full-day outing, which might be a bit tiring for some. The tour’s physical requirements also mean it’s best suited for those with moderate fitness levels who feel comfortable swimming and crawling through caves.

This tour is perfect for travelers eager to tick off unique Icelandic experiences without spending multiple days on separate excursions. Adventure lovers, curious explorers, and those with a sense of adventure will find it especially appealing.

The Itinerary: A Closer Look

The day begins with pickup in downtown Reykjavik (if you’ve selected the transfer option). From there, a comfortable, climate-controlled minibus whisks you away to Raufarhólshellir, Iceland’s fourth-largest lava tunnel. Here, the real excitement starts.

Lava Caving Adventure

You’ll be fitted with all necessary caving gear—helmets, headlamps, and sturdy clothing—and guided through the vibrant, colorful underground tunnel. Reviewers mention the unusual rock formations and lively scenery make this a captivating experience. Guides like Jonas and Apollo are praised for their knowledgeable and engaging explanations, making the geology come alive. Expect to do some crawling and climbing, which provides a good workout and a sense of discovery.

One reviewer highlighted the educational aspect of the cave, noting how their guides shared fascinating facts about volcanic activity and the formation of lava tunnels, adding depth beyond just the physical activity. The darkness and the sensory experience of navigating underground tunnels make this feel like stepping into another world.

Lunch Break

After the lava tunnel exploration, you’ll have a chance to refuel—lunch is at your own expense, so packing some snacks or a quick meal is wise. This break also allows a moment to reflect on the underground marvels before heading to the next highlight.

Snorkeling in Silfra

Next, it’s time for the main event—snorkeling in the Silfra fissure at Thingvellir National Park. Here, you’ll slip into a provided wetsuit and gear up for what many reviewers describe as a once-in-a-lifetime experience.

The water in Silfra is famously crystal clear, with visibility over 50 meters. You’ll glide between two continental plates—North America and Eurasia—marveling at the geological wonder that has formed over thousands of years. Guides like Siggy make sure everyone feels safe, offering clear instructions and patience, even for first-timers. Several reviewers noted how guides took photos during the dive, capturing memories of floating in a surreal underwater landscape.

While the water is cold, guides emphasize that only your hands and face might get wet, thanks to the excellent thermal insulation of the wetsuits. Reviewers mention that, with proper preparation, the sensation of swimming between tectonic plates is spectacular and not as cold as expected. The underwater scenery, combined with the thrill of the tectonic boundary, makes this a highlight for adventurous travelers.

Return & Reflection

After the snorkeling, warm up with hot chocolate and cookies, a thoughtful touch that helps everyone wind down. The return trip offers a chance to share impressions and photos, and you’ll be dropped back at your original meeting point, often with memories to last a lifetime.

Practical Tips for the Tour

Travelers should have a moderate physical fitness level and be comfortable swimming. The weight and height limits (45-120kg, 150-200cm) are worth noting, as well as the requirement to be able to swim independently.

Weather and safety are crucial considerations—if the weather is poor, the tour may be canceled, with options for rescheduling or a full refund. Always review the medical statement if you have health concerns, and note that pregnant women are advised against snorkeling due to the cold water exposure.

Bring warm outdoor clothes, thermal underwear, a change of clothing, towel, gloves, hat, and good hiking shoes. For those who wear glasses, contact lenses or prescription goggles are recommended, as snorkeling masks cannot accommodate glasses.

Authentic Experiences From Reviewers

Many travelers appreciated guides like Kevin, Siggy, and Mikka for their friendly, informative, and safety-conscious approach. One reviewer mentioned that their guides shared fun facts about lava and volcanic activity, making the lava tunnel exploration both fun and educational.

The snorkeling received glowing praise: “The water was so beautifully clear,” and “swimming through two tectonic plates was an otherworldly experience,” according to several reviews. Some noted that the wetsuits were restrictive and tight around the neck, but necessary to keep warm.

A common theme among reviews was the sense of achievement and awe, with many saying it’s an experience they’d repeat or recommend enthusiastically. However, a few noted organizational hiccups, such as unclear communication about meeting points or limited time underwater, so being prepared and attentive is advised.
