Davíðsgjá Dive Tour

Silfra's wilder, darker sibling

A hidden gem

In Thingvellir national park

Davíðsgjá is a fissure located in Lake Thingvellir, just like Silfra. The name directly translates as David's fissure. Davíðsgjá is popular among local divers but international divers are not frequent visitors.

Davíðsgjá is usually slightly warmer then Silfra. Divers walk straight into the water and after a shallow swim they enter the long, deep and narrow Davíðsgjá fissure.

The maximum depth of the dive in this fissure is 21 meters. Davíðsgjá often has incredible underwater visibility, although this varies and is more dependent on weather than in Silfra. Therefore, Davíðsgjá is sometimes called Silfra's wilder and darker sibling.

The top of the fissure in Davíðsgjá is actually about 7 meters underwater, which allows for more contact with the water in Thingvallavatn lake. It is therefore common that trout join the divers in exploring this fissure.

All divers on this Davíðsgjá Dive 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.

great dive

Diving in Silfra and DAVÍÐSGJÁ was amazing! Giancarlo was incredibly attentive and fun. He and the entire crew were so helpful and efficient, helping you get in and out of the dry suit and equipment, making the experience much more enjoyable.
really recommend taking the combo and not just Silfra.
