It is required to read the Snorkeling Handbook before booking.
Silfra is a rift in the Earth between two tectonic plates. Swim in the gap between Europe and North America in crystal-clear water.
You will experience a truly breathtaking experience as you drift peacefully through the electric blue waters of the Silfra Fissure. The water is astonishingly clear because it is glacial water from the Langjökull Glacier.
All year-round, the temperature in Silfra is about 2-4 degrees, but don’t worry! We provide fully insulated dry suits, and there will be a certified expert with you at all times. The water in Silfra is as pure as water can get: meaning that you can drink it during the dive!
Silfra is located in the heart of the historic Thingvellir National Park, a UNESCO World Heritage Site. The fissure opened after a strong earthquake in 1789. The North American and Eurasian tectonic plates continue to move farther apart at a rate of about 0.79 in (2 cm) every year.
To get to Silfra for your snorkeling trip, you can choose a pick-up from your selected location in Reykjavik. You may also choose to meet us on location at Thingvellir, where our friendly guides will be waiting for you.
The best part is that you don’t need any certification or previous snorkeling experience. The only requirements are that you’re healthy, adventurous, and able to swim!
Once you’re at Silfra, you’ll be given all the necessary equipment and put on your drysuit. You’ll swim in the “lazy current,” a stream of glacial water that flows slowly in the fissure. The pure glacial water filling the rift has been filtered by lava rock for decades, so feel free to take a sip of water while you’re there!
Marvel at the contrast between the deep blue water shades with the lime green and orange seaweed along with the dark brown rocks. You’ll discover spectacular rock formations as you glide through the four sections of Silfra:
When you finish snorkeling, you’ll be welcomed at the surface with cocoa and cookies to warm you up as you enjoy the panorama of Thingvellir. One more reason to add this experience to your bucket list!
Important note: Participants need to be comfortable in the water and be able to swim. You cannot participate if you are pregnant due to the small risk of cold water entering the suit.
Weight limit: 45-120 kg
Height limit: 150 cm -200 cm

If you plan to meet us at Silfra, please come to the Silfra car park at Thingvellir National park. Then once you have parked, walk about 400 m back up the road until you reach a smaller car park containing all the snorkel and dive vans. Once you have got there, then you can look for your guide. Please make sure that you arrive at Silfra car park early enough to meet your guide 15 minutes before the tour starts. Trust us, seeing the icy blue waters of Silfra is definitely worth it!

Mattia
Passionate for any water activity, I worked over and under the most beautiful waters of Europe and Asia for the last 15 years as a diving and sailing instructor, boat captain and tour manager. I'm always looking for the next skill to learn and ready to guide you safely through your next adventure.
Weronika
Weronika, I am a diving instructor from Poland. I came to Iceland for a while, I stayed for longer. I am a positive person, always smiling and waiting for challenges. Raised in cold waters, I am not afraid of any work and any challenge, so if you want to drown, do it only with me 😉. ‘Mayday Mayday we are sinking!’ ‘What . . . what are you sinking about?’
Ioannis
Ioannis (John) Scuba Instructor and CBO (Chief Barbecue Officer) from Greece, I started my diving journey in the warm waters of the Mediterranean sea and Greece. I like the challenges, and this is why I came to Iceland. I realized that I love COLD water and Silfra, and now I am very enthusiastic about any activity out in the cold arctic environment. I love guiding and teaching people and creating lifetime experiences for them.
Federica
My name is Federica, but I go as Fede. My diving journey started in 2020 in the beautiful waters of Sardinia and my passion for challenges and extreme activities took me to Iceland. Back then, I would have never imagined to build a life here... but fortunately I did! I have been here for almost 3 years and counting. Water is definitely my element, I am very passionate about my job, animals, the environment and food, but only if it's vegan (sorry Mamma for my vegan lasagna...). Being Italian is for sure a big chunk of my personality. Can't wait to show you the magic of Silfra!
Marcin
Marcin, diving instructor from Poland. I also love hiking, traveling, sport, outdoor activities, movies, books and many others. I enjoy learning and trying new things, especially overcoming my own fears. I enjoy specific sense of humor.

Yes, there are two toilet facilities at Silfra.
Occasionally fish venture into Silfra from Þingvallavatn lake, but they will quickly swim back as they don’t like the cold glacier water. However, there is a lot of colorful seaweed including a bright green variety known as ‘’troll hair’’, which makes the fissure unlike anything on the surface.
Silfra can be up to 60m deep. However, when you’re diving in Silfra than you will go about 7 to 12m deep, and the maximum diving depth that is permitted is 18m.
