The Unique Setting in Thingvellir National Park

The park’s fissures and cracks are visible above ground, but it’s underwater where the true marvel unfolds. The Silfra fissure is a deep crack in the earth, filled with crystal-clear water, offering an unparalleled view of the continental boundary.

The site’s status as a UNESCO World Heritage site emphasizes its geological importance and preservation, making the tour not just an adventure but an educational journey as well.

What the Dive in Silfra Looks Like

During the guided tour, you’ll explore four sections of the fissure. The entry point takes you to Big Crack, the narrowest segment where continental plates are so close you could touch them. From there, the Silfra Hall opens up, revealing a broad space filled with vibrant colors and incredible visibility.

Next, the Silfra Cathedral reaches depths of 23 meters, where the clarity allows you to see the intricate details of the underwater formations. The final stop is in Silfra Lagoon, known for its extremely clear water and tranquil surroundings.

Each section offers a different perspective on the geological marvel, with the colors and visibility creating a surreal underwater landscape. The full spectrum of colors appears as sunlight interacts with the water, making this a visually spectacular experience.

The Experience of Diving in Cold Water with Dry Suits

Despite the year-round temperature of 2°C, divers stay warm thanks to provided dry suits and warm undersuits. The dry suit keeps you dry and comfortable, allowing you to focus on the stunning scenery rather than the cold.

Guides brief participants thoroughly on dry suit operation and safety procedures, especially crucial for those with dry suit diving experience. The short dive time—about 30 minutes in the water—ensures safety and enjoyment without fatigue. The hot chocolate and cookies afterward provide a cozy way to warm up and reflect on the experience.

The guides’ expertise and attention to safety make this a secure and enjoyable adventure, even for those new to dry suit diving. However, participants must have PADI Open Water certification or an equivalent and dry suit diving certification with recent logged dives. Restrictions apply for those under 17 or with certain physical conditions, so check your qualifications before booking.
