SILFRA ICELAND TOURS

Have you ever been diving between two continents? Do you want to go inside one of the most crystal clear waters of the world? Join one of the diving or snorkeling tours in Iceland and you will discover one of the best dive sites in the world. The Silfra Iceland tours take place in Silfra canyon, where the Eurasian and North American tectonic plates divided, a truly special place located in Thingvellir, a national park that is a UNESCO heritage and is part of the Golden Circle of Iceland.

What is Silfra and where is it?

Silfra is a freshwater fissure formed by the divergent movement of the Eurasian and North American tectonic plates. It was created in 1789 and is located within Thingvellir National Park, approximately one hour by car from Reykjavík in the area known as Iceland’s Golden Circle. The fissure is spring-fed by groundwater originating as meltwater from Langjökull, Iceland’s second-largest glacier, about 50 km north of Þingvallavatn Lake. This water is highly filtered, exceptionally clear, extremely pure, and drinkable. With visibility exceeding 100 meters underwater, Silfra is considered one of the best diving and snorkeling locations in the world. Its position between tectonic plates means the fissure is constantly changing, forming new caverns and tunnels over time.

What is Thingvellir National Park and the Golden Circle?

Thingvellir National Park, a UNESCO World Heritage Site since 2004, is one of Iceland’s most important natural and historical areas. It was the site of the first Icelandic Althing parliament in 930 AD, and visitors can clearly see the divide between the Eurasian and North American tectonic plates. The park is part of the Golden Circle, a popular circular route that starts in Reykjavík and includes other iconic sites such as Gullfoss waterfall and the Geysir geothermal area. Thingvellir has also been a filming location for series like Game of Thrones.

What activities can you do at Silfra?

Silfra is renowned for diving and snorkeling, offering an unforgettable experience swimming between two continents. Beyond water activities, the Golden Circle attractions are all nearby: Gullfoss waterfall, Geysir geothermal area, and Thingvellir National Park with its hiking trails. This means group members who prefer not to dive can explore the park on foot while others dive or snorkel. Being only an hour from Reykjavík, you can combine Silfra with other activities, including a visit to a geothermal pool like Fontana or the Secret Lagoon.

Requirements for joining a Silfra tour

• Diving tours: A dry suit diving certificate or a minimum of 10 recorded dry suit dives in the last two years is required. Beginners can take a 2-day diving course to qualify.

• Snorkeling tours: Physically fit, able to swim, and comfortable in water. A dry suit will be worn, which can feel tight and restrictive.

• General: Must understand English for safety instructions. Age, weight, and height restrictions vary by tour; check individual tour details.

Departure points for Silfra tours

Tours may depart from Reykjavík or directly from Silfra in Thingvellir National Park. For tours starting at Silfra, you need a car to reach the park (approx. 1 hour from Reykjavík). The meeting point is usually at the Silfra car park (“Thingvellir Parking P5” on Google Maps), followed by a short 400-meter walk to the guide and dive vans.
