The Silfra fissure is a one of a kind dive site. The fresh glacial water is crystal clear and visibility can reach well over 100 meters. It is regularly voted one of the best cold water dives in the world.

SIlfra is located in the tectonic rift valley of  Thingvellir National Park in SouthWest Iceland. It is part of the tectonic plate boundary between the North American and the Eurasian tectonic plate. This tectonic plate boundary is called the Mid-Atlantic ridge and stretches from Arctic to Antarctica along the floor of the Atlantic ocean. Luckily Iceland and Silfra lays in its way, giving us the unique opportunity to dive in between.

The water temperature is a constant 2-4° C all year round, which provides excellent visibility during all seasons. Top quality cold water dive equipment, including dry suit rental is included in all our tours.

We offer complimentary pick up from Reykjavik for all dive tours.

The tour includes

  • Free pick up from Reykjavik
  • Two dives in the Silfra Fissure (only 1 dive if below 0° C)
  • All rental equipment
  • Experienced guide
  • Hot chocolate and cookies
  • National park entrance fee


Our most popular dive tour!
Underwater visibility can extend to over 100m, combine this with the geological significance and you get why Silfra is often voted in the world’s top 5 dive sites.

Prerequisites for diving:

Dry suit certification or a minimum of 10 logged dry suit dives within the last two years are required to participate in this tour. The dive guide will check your certification and verify your dry suit experience before the tour starts. Without this experience you are not allowed to dive.

Age limit:
18 years old

You need to understand and be able to communicate in English.

If you do not have the required dry suit experience we really recommend a snorkel tour for you, it’s very easy and relaxing and a great way to see Silfra. If you want to learn how to dive in a dry suit we offer the PADI drysuit diver course here at Scuba Iceland (available May – October).

Difficulty: Demanding.
You need to be confident that you can control your bouyancy in a safe way, as you will step straight into water 30+ meters deep. There is no descent line in Silfra.

This tour involves a little hiking in your fill dive equipment as we are diving in a pristine national park and as such we can’t build anything on site. The walk from the exit of the dive site is approx 500 meters. The weight of the dive gear and the weight belt will be somewhere around 30-40 kg.

If the temperature drops below 0 degrees Celsius then we only do one dive as all of the equipment will begin to freeze in-between dives. We will try to extend the single dive as much as possible though to give you the best experience. This will only happen in the winter.

Please bring:
Your PADI Open Water diving certification or equivalent along with your Dry Suit Diver certification, or logbook documenting 10 Logged drysuit dive within the last two years. Without these, you are not allowed to dive. Warm long underwear and thick socks are recommended to wear under the dry suit.

Pick up service:
We offer complimentary pick up service for all of our dive departures. Please note we only offer pick ups from the Reykjavik Hotels/hostels listed in the drop down menu. Let us know if your accommodation is not in the list, and we will advise your closest pick up location.

Meet on location:
If you are meeting us on location, the meeting point is Silfra car park in Thingvellir National Park. Click here for driving directions to where you can park your car (parking “Thingvellir P5”).

To meet your guide: Walk 400m back along the road until you reach a smaller car park with all the dive and snorkel vans, and look for your guide/Scuba Iceland vans. Please be ready in the Silfra car park to meet your guide 15 MINUTES before your tour is due to begin.

The Icelandic dive community has divided Silfra into four main parts, and during your dive you will get to experience all these. The entry point will take you into the Silfra Deep Crack. Here you will step straight into the deep, blue water where you can see all the way down to the bottom at about 25 meters. You will also be able to see some openings to the deep lava tubes and caves resting underneath Silfra. The caves reach an impressive depth of 63 meters. On our dive tours we will, however, stay in the open water with free access to the surface and dive to a maximum depth of 15 meters.

Your dive guide will lead you from the Deep Crack into the Silfra Hall. Here the fissure opens up and you will swim along this wide and bright corridor. This is the perfect place for a photo as lots of light reaches the surrounding lava rocks.  You might also meet a Trout or an Arctic Char, on it way in from lake Thingvallavatn.

The hall will eventually narrow off and this is the sign that you will now enter the most famous part, the Silfra Cathedral. Now the fissure gets deeper, clearer, bluer and we dare to promise that you have never seen anything just like this!

Towards the end of the Cathedral, keep a close eye on your guide as he or she will now turn around and point to the left, meaning ”please follow me to the left”. This will lead you into the Silfra Lagoon which is different from the previous parts you have already experience. In the lagoon the water is only 5 meters deep but you will fall in love with this place. Most days you can see from one side of the lagoon all the way to the other side, an impressive 140 meters! We finish the dive by slowly swimming across the lagoon until we reach our exit point where we ascend.

After surfacing we offer you a chance to warm up, as well as a good work out, as we now have a 400 meters walk back to the car. This is a bit challenging with all the gear on, but it is all part of the Icelandic dive experience!

Amazing experience. Small group size. Memorable.
In comparison to the groups from the other company with had over 15 people per group, I was very glad I went with Scuba Iceland. The more personal attention and smaller ratio helped with the experience.
