Imagine floating weightlessly in a glacier-fed pool, surrounded by a landscape so surreal it feels like you’ve landed on another planet. That’s exactly what the Silfra Fissure Snorkeling Tour offers—an extraordinary experience in Iceland’s Þingvellir National Park, where you get to snorkel between the North American and European tectonic plates. Priced at $169 per person, this three-hour adventure is guided by certified professionals, with plenty of opportunities to snap free underwater photos that will leave you with memories long after you’ve returned home.
One of our favorite aspects? The crystal-clear waters, which reveal a stunning view of the fissure’s depths, and the knowledgeable guides who make even first-timers feel safe and informed. Also, the hot drinks and cookies afterward are a perfect way to warm up and reflect on what might be one of the most unique sights you’ll ever see.
On the less rosy side, the tight fitting dry suits can be a bit uncomfortable for some, especially around the neck. If you’re sensitive to constriction or claustrophobic, this is worth noting. But for most travelers, the thrill of gliding through these waters outweighs the minor discomfort.
This tour suits those who are comfortable in water, able to swim, and eager to see something truly different. It’s perfect for adventure lovers, nature buffs, and anyone wanting a story to tell that’s as impressive as Iceland’s landscapes.

Location & Setting
The Silfra Fissure lies within Þingvellir National Park, a UNESCO World Heritage site renowned for its geological and historical significance. The fissure itself is a crack in the earth where the North American and Eurasian tectonic plates are slowly drifting apart—about 2 centimeters a year—making it a geological spectacle. It’s an experience that combines spectacular scenery with a touch of science, all framed by the rugged Icelandic landscape.
What the Tour Includes
Starting at the Troll Expeditions meeting point, you’ll first gather for a safety briefing—usually about 30 minutes. Here, your guide will explain how to use the equipment, what to expect in the water, and answer any questions. The gear includes a high-quality dry suit, designed to keep you warm and dry despite the icy temperatures.
Following this, you’ll walk to the fissure itself, a walk of about 30 minutes, which gets you familiarized with the surroundings and allows time to soak in the natural beauty of Þingvellir.
The Snorkeling Itself
The actual snorkeling session lasts around 50 minutes. You’ll swim through the crystal clear waters, which are filtered and fed directly from nearby glaciers. The water’s transparency means you can see deep into the fissure, revealing vibrant colors and rock formations that look almost alien. Many reviews mention how spectacular the views are, with some describing the experience as “floating weightless over a beautiful landscape.”
Guided by your instructor, you’ll have the chance to observe local plant species, such as dwarf char, and marvel at the colors of the glacier meltwater, which range from striking blue to deep turquoise. The experience is often described as surreal, with plenty of opportunities for photos—most tours include a free GoPro session.

Considerations and Practical Tips
While most travelers rave about the experience, a few point out some minor challenges. The dry suits, although excellent at insulation, can feel constricting around the neck—some describe the fit as very tight, which could be uncomfortable if you’re sensitive.
