Experience snorkeling between tectonic plates in Iceland’s Silfra Fissure for $146. Enjoy crystal-clear waters, expert guides, and stunning geology on this small-group tour.

The Silfra: Snorkeling Tour Between Tectonic Plates offers an exceptional opportunity to float in the crystal-clear waters of Silfra Fissure, located within Thingvellir National Park in Iceland. Priced at $146 per person, this guided tour lasts from 2.5 to 5 hours, making it an accessible adventure suitable for most travelers over 12 years old who are comfortable in water and able to swim. The tour is notable for its small group size, limited to 6 participants per guide, ensuring personalized attention and safety.
What sets this experience apart is the chance to stand between the Eurasian and North American tectonic plates—a geological wonder visible in the narrow Big Crack and from the Silfra Hall. The tour provides all necessary gear, including wetsuits and dry suits, to keep participants warm in the freezing but surprisingly comfortable waters, which offer up to 300 feet of visibility. After the snorkel, guests enjoy hot chocolate and cookies while chatting with guides, adding a warm, social finish to the adventure.
While the timing flexibility ranges from 2.5 to 5 hours, the experience’s core activity—about 45 minutes in the water—delivers unforgettable views of glacial meltwater, boulders, and underwater formations. The tour begins at the Silfra Meeting Point in Thingvellir National Park, with options for pickup or easy self-drive access. This is a well-organized, safety-focused experience backed by over 400 reviews and an impressive 4.8-star rating.

This tour departs from the Silfra Meeting Point within Thingvellir National Park, a UNESCO World Heritage Site. Travelers are instructed to drive along road 36, where they will see the company cars parked at the designated meeting area.

The tour includes a safety briefing before entering the water, where guides explain proper techniques and safety protocols. Once in the water, you’ll be led through the Big Crack, where the continental plates are closest, and into Silfra Hall, an expansive underwater chamber. At 23 meters deep, participants feel as if they are flying over the underwater terrain, observing boulders, glacial silt, and the vibrant blue waters that owe their color to the pure glacial meltwater.
The guided snorkeling lasts approximately 45 minutes, during which guides point out notable features like lake Thingvallavatn in the distance. For most, the experience is surprisingly warm and comfortable, thanks to the dry suits and thermal undersuits provided. Afterward, there’s free time of about 30 minutes for photos, relaxing, or exploring the area further.

All necessary snorkeling gear is included, and guides help participants fit wetsuits and dry suits properly. The suits are designed to block out the cold, making the experience far more comfortable than one might expect given the water temperature of around 38°F (3°C). Participants are advised to bring warm clothing, especially thermal underwear and wool socks, for the time spent on land.
The heated van offers a warm, dry space to change clothes, and hot chocolate and cookies are served at the end to warm up after the underwater adventure. Guides are praised for their knowledge, attentiveness, and friendly attitude, often making the experience both educational and fun.
