What Is the Silfra Snorkeling Tour All About?

This tour is a chance to float in the Silfra Fissure, a crack in the Earth’s crust that marks the boundary between North America and Europe. Located within Þingvellir National Park, a UNESCO World Heritage Site, this spot is famous for its crystal-clear glacier meltwater and the fact that every year, the two tectonic plates drift a tiny bit farther apart.
The tour lasts about 3 hours, including safety briefings, gear fitting, and the actual snorkeling. The core activity involves swimming through the water for approximately 50 minutes with a guide, exploring the underwater landscape, and keeping an eye out for local marine life like dwarf char. You’ll also get hot drinks and cookies afterward, which is a nice touch after the chilly water.
Guides are certified PADI professionals, which reassures many travelers about safety and expertise. They’ll give a safety briefing, help you get suited up, and support you throughout the experience. The guided aspect is especially helpful since many reviews mention guides being very friendly, attentive, and clear in their instructions.

After a safety briefing that lasts around 30 minutes, you’ll get all the necessary snorkeling gear—wetsuits, dry suits, masks, and fins.

Following gear fitting, there’s about 30 minutes of on-foot preparation. This includes getting familiar with your equipment and listening to safety instructions. Once ready, you’ll enter the water for your guided snorkeling session, which lasts around 50 minutes.

The tour concludes back at the starting point, with an opportunity to view the photos taken by guides via GoPro. These photos are included in the price, providing a fantastic keepsake without extra charge.
Throughout the experience, guides often share interesting insights about the geology of the area and the tectonic plates, making it both fun and educational.
