The Experience in Detail

Silfra: Snorkeling Tour Between Tectonic Plates - The Experience in Detail

Starting Point and Logistics

The tour begins at the Silfra Fissure, within Thingvellir National Park—a UNESCO World Heritage Site renowned for its geological significance and stunning landscapes. You’ll meet at a designated parking lot, where your guides’ cars are parked, and then proceed on foot to the entry point, which takes about 10 minutes. The meeting location is straightforward, and the tour provider, DIVE.IS, offers clear instructions on where to arrive.

The Safety Briefing and Gear Up

Once gathered, you’ll receive a thorough safety briefing. Guides emphasize safety while also making sure you feel comfortable before entering the water. The gear provided is impressive: snorkeling gear, wetsuit, drysuit, and warm undersuit. Many reviews mention the quality of the gear—crucial, since Iceland’s water averages around 2°C (36°F). The wetsuits and drysuits do a good job of keeping you dry and warm, with some reviewers noting that the suits are so effective that the water doesn’t feel as cold as expected.

You’ll also be comfortably changed in a heated van, which is a thoughtful touch for chilly mornings. The gear-up process is the less glamorous part of the trip, but it’s essential for safety and comfort once in the water.

Snorkeling Through the Big Crack and Silfra Hall

The core of the adventure involves about 45 minutes in the water, floating through the Big Crack, the narrowest section where the tectonic plates are just inches apart—you could almost touch them. Then, you’ll pass into the Silfra Hall, a wider chamber where the water’s clarity lets you see all the way to Lake Thingvallavatn, over 150 meters away.

Guides often point out the fascinating geology—how the plates are drifting apart at a rate of about 2 centimeters per year. The water is a mix of glacial meltwater that has traveled underground for decades, which accounts for its remarkable purity and clarity.

When you reach Silfra Cathedral at 23 meters deep, the sense of flying over boulders and silts is extraordinary. It’s a surreal feeling, floating in a pristine, underwater landscape where you can observe the textures of rocks and underwater features in incredible detail.
