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.

Minimum requirements for diving:
Must be at least 18 years old and understand instructions in English. Age limit: 16+. Weight limit: 45-120 kg. Height limit: 150cm – 200cm.

In order to come on the tour, you need to have dived within the last two years. You have to have an Open Water certification from any recognized diving organization and a Drysuit certification or 10 logged drysuit dives within the last two years.

You will need to complete our Dive Silfra medical form. It can be viewed using this link SILFRA DIVING MEDICAL RELEASE. This will need to be completed in full and bought to site on the day.

If your a little unsure about diving in a drysuit we really recommend a snorkel tour for you, it’s very easy and relaxing and a great way to see Silfra. Or we offer the PADI drysuit diver course here at Scuba Iceland (May – October) with your final certification dive being done in Silfra fissure.

Difficulty: Demanding.
This tour involves a little hiking with your 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 500m. Drysuit diving in itself is also a challenge and requires much more weight than Wetsuit diving.

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.

Please bring:
Your PADI Open Water diving certification or equivalent from any recognized diving organisation, Your drysuit certification or logbook documenting 10 Logged drysuit dive within the last two years. Without your these, you are not allowed to dive. Good warm long underwear and thick socks are recommended.

We don’t guarantee photos on a dive tour as the priority for the guide is looking after you and helping with the drysuit, once everything is ok with the diving the guide will then look at taking photo’s which you then have the option of purchasing at the end of the day.

Pick up service:
We offer a pick up service for all of our departures, this is charged at 3000 ISK per person. Please note we only offer pick ups from the Reykjavik Hotels listed in the drop down menu

Meet on location:
All tours start at Thingvellir Information Centre. Click here for driving directions to the meeting point. If you need a pick up from Reykjavik this can also be added into your tours when making the booking


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. Also, from a cost point of view, they don't charge extra 5000 isk like some companies for pick up.
