Silfra’s bigger cousin!
Thingvallavatn is the lake that Silfra feeds into and it is the largest natural lake in Iceland covering 84 km² and reaching a depth of 114m. On the north corner, there is a crack at the bottom that is a much bigger version of Silfra.

This crack is a favourite dive among Icelandic divers called Davidsgjá or David´s Crack, depth starts at around 10m and we usually drop to 25m. The water can be crystal clear just like Silfra and there is also a great chance of seeing local lake fish such as arctic char and trout.

Minimum requirements for diving:

A minimum age limit of 18.

Drysuit certification or 10 logged drysuit dives within the last two years is required for this tour. Your dive guide will check your certification and verify your dry suit experience before the tour starts.

Difficulty: Demanding.
This tour involves a little hiking with your equipment due to the remote location.

The lake is rarely affected by weather during the summer season.

Please bring:
Your Dry Suit certification or equivalent from any recognized diving organization, or a logbook showing a minimum of 10 logged dry suit dives. Without your certification you are not allowed to dive. Bring good warm long underwear and thick socks to wear under the dry suit.


When we first get to the site you will enjoy the peace and quiet of having no one else around you when gearing up because of the secluded location where we enter the lake. This peaceful and remote feeling will then follow you all the way through your dive, as the only life you will see in the water part from your guide and your dive buddy might be some Trout and Arctic Charr.

We start the dive by swimming straight out into the lake for a few minutes, here the visibility is usually 10-20 meters, but just keep on swimming and when you reach the actual fissure in the lake floor the water goes cold and often crystal clear. We have seen up to 100 meters visibility here many times!

Max depth on this dive site is around 30 meters, but we will base our depth on your experience and confidence.

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.
