Silfra and Aurora Borealis
The clearest water and most dazzling sky
This tour combines two spectacular Icelandic vistas: the underwater sights in Silfra and the Northern lights.
A snorkeling adventure in the famous Silfra fissure is an unforgettable experience, there is a reason this Snorkeling Tour was awarded the best tour in Iceland and 10th in the world on the 2024 Best of the Best Traveler's choice awards by Tripadvisor.

- Our guides are all experienced PADI divemasters and instructors that have been through professional training before running any of our tours.
Your adventure begins with the snorkeling tour of Silfra. This is a self-drive tour so you will meet us at the Silfra meeting point in Thingvellir National Park. Silfra, the famous fissure between the Eurasian and North American tectonic plates, provides an underwater experience unlike anywhere else on earth. Floating in the crystal clear glacial water will give you the sensation of flying as you pass through an expansive canyon created by the slow separation of the tectonic plates. You will be provided with a dry suit and an undergarment to keep you dry and warm while in the near-freezing water. We recommend that you wear thermal long-underwear and wool socks for additional warmth. Make sure to drink some of the Silfra water while you are snorkeling! Who knows when you will be able to drink water so pure again. After your 30-40 minute snorkeling session in Silfra, you can explore the Thingvellir area as you wish.
Your northern lights hunt will begin later in the evening when you make your way the 20 minute drive from Reykjavík to Aurora Basecamp, a brand new Northern Lights Observatory where you will get tips on how to spot them, how to hunt for them in your rental car, how to take photos of them on your camera and much more making it a perfect starting point for your Northern Lights hunt in Iceland. At Aurora Basecamp you will also experience a unique indoor simulation of the Northern Lights.
Also known as aurora borealis, northern lights are caused by the effect of solar flares on earth's athmosphere. They appear in many forms and colors, ranging from green and white to pink and purple. Sometimes they appear as a dancing streak across the sky. At other times, they'll appear as lasers shooting down from outer space. As the possibility of viewing the northern lights depends on both solar activity and weather conditions here on earth, it is not possible to guarantee the northern lights. However, the simulation in the Dark Park at Aurora Basecamp allows you to see a simulation so real that you will not be disappointed if you are not able to catch the real lights.
This is a self-drive tour. Meeting point for Silfra Snorkeling is at Thingvellir national park. The drive from Reykjavik is about 1 hour. Meeting point for the Northern Lights tour is at Aurora Basecamp. The drive from Reykjavik is about 20 minutes.

-
Do you see any life in Silfra?
-
Although there is plenty of life in Silfra, most of it is either plant life or micro-invertebrates, which are not visible to the human eye. Silfra is home to a unique amphipod called Crymostygius Thingvallensis found only in Thingvellir Lake and the surrounding fissures, such as Silfra.
In regard to fish life, there are three different species of fish that live in the lake: Brown Trout, Arctic Char and Sticklebacks, however, only the Arctic Char visit the fissure; they are frequent visitors during mating season in August and September. Throughout the rest of the year, the only fish who live in the Silfra fissure are the Dwarf Char, a subspecies of the Arctic Char. These range in size from a few centimeters to approximately 10cm maximum and live down in the darker recesses near the rocks and as such are not often spotted by divers or snorkelers.
