Extraordinary 4-Hour Wetsuit Free Diving and Snorkeling Tour in Silfra

Experience one of Iceland's most captivating geological wonders on this extraordinary free dive tour in the Silfra ravine. This three-hour adventure puts travelers on a wetsuit to explore Thingvellir National Park's most famous fissure with crystal-clear waters.

The action begins when you meet a friendly expert guide in the carpark near the Silfra fissure. The guide will give a brief introduction to the tour and provide all the necessary free-diving accessories, including a snorkel and a wetsuit. Unlike diving in a drysuit, sporting a wetsuit gives you more freedom and flexibility when exploring the Silfra ravine inside Thingvellir National Park.

 A UNESCO World Heritage site, Thingvellir National Park is one of the most celebrated sites in Iceland because of its exceptional natural and historical significance. Thingvellir National Park is famous for its geological features, as it sits directly on the boundary between the North American and Eurasian tectonic plates. 

Beyond its geological wonders, the park holds a deep cultural significance. It was the site of the world's first parliament, the Althing, established in 930 AD. However, you'll focus on exploring the Silfra fissure. The crystal-clear waters of Silfra come from underground springs that filter through volcanic rock, providing visibility of up to 100 meters (328 feet).

Your guide will give you all the safety equipment and essential reminders before suiting up in your wetsuit. Once you and your group are ready, the guide will take you to the staircase where you can safely enter the Silfra's waters. As you dive into the Silfra ravine, you'll notice the cold water, with a constant temperature ranging from 2-3° Celsius (35-to 37° Fahrenheit). 

Once you drift through the deep crevices and narrow channels, you'll start to warm up. Moreover, you'll begin to encounter the colorful underwater flora and volcanic rock formations.  The occasional fish, such as small trout, can also be spotted, although wildlife is sparse due to the water's cold temperature and clarity.

However, the most magical aspect of Silfra is the sensation of swimming between two continents. As you drift through the fissure's narrow passages, you'll literally be swimming between two tectonic plates.

Apart from the Silfra water's remarkable visibility, it is also one of the cleanest in the world. The water in Silfra comes from melted glacial ice from the nearby Langjkull glacier. Interestingly, the water has been filtered for many years through porous lava, making it pristine and safe to drink.

After diving and snorkeling around Silfra, you'll return to the parking lot for a cup of warm chocolate to end the tour.
