Dive between the tectonic plates
in the clearest water in the world
On our Diving Silfra Day Tour you will dive into the most unique body of water in the world with unparalleled visibility. Silfra is a crack in the Earth ripped open by the movement of the North American and Eurasian tectonic plates. The crystal clear glacial water providing over 100 meters of underwater visibility has been filtered for decades through underground lava rocks. The underwater scenery that you experience on your Diving Tour is found nowhere else on Earth.
The snorkeling tour in Silfra operated by DIVE.IS is the best tour in Iceland and 10th in the world on the 2024 Best of the Best Traveler's choice awards by Tripadvisor.
How to get to your Diving Silfra Tour
Your Silfra Diving Tour begins with pick up from your accommodation in Reykjavík. During the one-hour drive to Thingvellir National Park, your guide will introduce you to the unique geological and cultural history of Silfra and the surrounding Thingvellir area. If you have your own transportation to Silfra, you can also meet us directly at the Silfra meeting point in Thingvellir National Park.
The structure of your Diving Tour
The Silfra Diving Tour includes one dive which will take about 30-40 minutes, with a maximum depth of 18 meters.
At the Silfra Meeting Point, your guide will give you a detailed briefing of the dive site and will then assist you in setting up our dive equipment. We use high quality BARE and Aqualung brand SCUBA equipment and APEX or Aqualung regulators.
All divers on this Silfra Diving Tour must have dry suit diving certification OR 10 logged dry suit dives within two years of the Silfra tour date. These 10 dives must be confirmed with written proof signed by a diving instructor.
In case you do not fulfill these requirements, you can take PADI Dry Suit Diver Certification Course (or equivalent) before coming to Iceland. Or you can also take the Dry Suit Diver Course & Diving Silfra 2-Day Package here with us in Iceland! Alternatively, you can also Snorkel in Silfra instead of scuba diving.
Then it’s time to take the plunge and experience diving into Silfra’s pristine, crystal clear water. Naturally filtered for decades by Iceland’s volcanic basaltic rock, you can easily take a sip during your dive – you won’t find purer drinking water.
Explore the four Silfra main parts on your Diving Tour
During your dive you will explore the four main parts of Silfra. You will float through the narrowest section called Big Crack first, where you can have your ‘Dive Between the Continents’ photo taken. As the Silfra fissure widens you will find yourself in Silfra Hall with the possibility of spotting local ducks and geese paddling overhead.
Near the opening to Thingvallavatn Lake we enter the majestic Silfra Cathedral – the deepest point of this amazing diving tour. If there are divers ahead, you will easily see the mesmerizing ‘chandelier effects’ of their rising bubbles. Lastly, your dive will conclude in the relaxed, endless visibility of Silfra Lagoon.
After the dive, we will make our way back along a 250 meter path with our dive gear and then warm our hands and spirits with hot chocolate and cookies. Don’t hesitate to let your guide know if you need assistance with your gear on the walk back!
If you have friends or family who are not certified divers but would also like to experience Silfra, they are welcome to join our Snorkelling Silfra Day Tour.
We would like to bring your attention to the fact that there are only 3 divers with each guide in Silfra. If three couples are diving together (with 2 guides), the unfortunate circumstances will occur that one of the couples has to split up and not enjoy Silfra together. If you would like to avoid this situation, you can book our Diving Silfra Buddy tour, a semi-private option for you and your dive buddy.
Silfra fissure is located at Thingvellir National Park which is on the Golden circle, a very popular sightseeing route in Iceland. Other sightseeing locations on the Golden circle are Gullfoss waterfall, Geysir hot spring and Kerið crater.

FAQ
-
Are photos always taken on the Diving Day Tours?
-
Our dive guides always bring along an underwater camera on the dives at the breathtaking Silfra and other marvelous dive sites. During these dives, our dive guides strive to capture as many splendid underwater photographs as possible. However, the safety of our divers is our utmost priority, and there may be occasions when the dive guide chooses to focus solely on dive safety during challenging conditions or with less confident divers. In such cases, it is possible that only a few or no photos are taken. We sincerely appreciate your understanding should this be the situation.
Typically, the photos from the dives are available for purchase after your incredible dive tour. For more information, please visit our our Souvenir page.

-
Can I bring my own dive equipment?
-
Yes of course! You are welcome to bring your own dive equipment to Iceland. Just make sure that your dive equipment is serviced and rated for cold-water diving. As a standard, we use DIN cylinders; please let us know in advance if you require a different set-up for your dive equipment, and we will do our best to satisfy your request.
Please note, we do not offer any discount on the equipment that you might bring. DIVE.IS does not take any responsibility for any equipment you may bring on the tour.
-
-
Can I take the PADI Dry Suit Diver Course and dive Silfra?
-
To dive Silfra you are required to have either a drysuit diver certification or drysuit dive experience. We have therefore created a 2-day Drysuit and Silfra Combo Tour. During this tour, you will complete your PADI Dry Suit Diver Specialty Course on the first day and, upon completion, participate in the Diving Silfra Day Tour on the second day.
-
-
Do you pick me up at my hotel or do I need to come to a pick up point?
-
We will either pick you up at your hotel in central/downtown Reykjavik, or, if you are staying on either Hverfisgata or Laugavegur we will pick you up at a designated pick up location If you are however staying outside of Reykjavik, you will unfortunately need to arrange your own transport into Reykjavik, preferably to the BSI bus station, where we will then pick you up. You can then of course also meet us in the National Park Thingvellir if you have your own transport.
-
-
How far is it to Silfra from Reykjavik?
-
It is about 60 km from Reykjavik to Silfra and it takes a little less than one hour to drive the distance by car, given the weather conditions are good. If you choose to drive to Silfra yourself and don‘t know the way, we recommend you to study the map before you hit the road. Silfra is located in Þingvellir National Park, which is a bit different from other national parks. At a point, when you turn into road 36, you will feel like you are driving into the middle of nowhere. Please do not turn around, just keep going straight until you see our company cars which are parked at the Silfra Meeting Point, you then drive a little further to parking lot P5 to park. If at anytime you feel lost please do not hesitate to call our office for help.
-
-
How long are the Silfra dives?
-
Each of the Silfra dives is usually between 30 and 45 minutes, depending on air consumption, diver ability and customer comfort.
-
-
I am diving and my friend wants to snorkel, is that possible?
-
Yes of course! Our dive and snorkel tours start at the same time, so please choose the tours that are in the same time slot. If you need transportation from Reykjavík, then we can pick you up together in the same van. Please be aware that not all dive/snorkel tours offer pick-up. Once at the site, divers and snorkelers are split into separate groups with different guides, but it is a small area and you will surely see each other. Please note that National Park regulations do not allow divers and snorkelers to be in the same spot in the water at the same time, you will therefore enter the water at different times with different guides.

-
Is there anything to see around Silfra?
-
Silfra is located in Thingvellir National Park, one of the main sites of the Golden Circle. It is a stunningly beautiful area, as well as being one of Iceland's most important historical sites. There are many walking trails and interesting landmarks around the park and close to Silfra, and many of the areas have information signs telling you about the historical & geological aspects of the area around Silfra and Thingvellir. More details can be found on our dedicated blog post.
-
-
What is the best time of year to dive Silfra?
-
There is no best or worst time to dive Silfra. Every season and every weather has its advantages. A calm and overcast winter day will be amazing with beautiful reflections in Silfra´s water surface. A windy summer day with waves will cast sun ripples onto the Silfra bottom... a sight you will never forget. Generally in the summer, there are more snorkelers & divers at Silfra, so the winters are calmer, but winter surface conditions can also be more challenging with regard to weather and cold.
-
-
Why do I need to fill out a Diving Silfra Medical Statement?
-
Every diver joining our Silfra Diving Day Tour needs to fill out the Diving Silfra Medical Statement to make sure that he/she understands the difficulties and risks associated with the Silfra dives as listed on the left-hand side of the form and by completing the medical questionnaire on the right-hand side of the form the participant confirms that he/she is fit and healthy to join the Silfra Diving Day Tour. This is done so that all divers enjoy a safe and happy dive tour.
