Shore-entry Icelandic fissure with drysuit rules, trout, and a narrow freshwater slot.
About Davíðsgjá
Davíðsgjá is a cold-water fissure dive in Lake Thingvallavatn, shaped by shore access, a narrow slot, and strict park rules rather than by current or surf. It is a quieter Icelandic rift than Silfra, with trout in the water and a shallow-to-deep progression that rewards careful buoyancy. The site suits divers who are comfortable in drysuit conditions and want a serious freshwater dive with strong natural geometry.

Local Intel For Davíðsgjá
Community notes to help plan your visit.
Scuba Diving
A drysuit, buddy discipline, and slow trim are the key parts of the dive. The site is about the fissure geometry, not a fast swim.
Freediving
Not a freedive-first site. It can be snorkeled, but the full experience is built around cold-water scuba gear.
Snorkeling
Snorkeling is permitted, but only with full cold-water equipment and the ability to handle a long, cold shore swim.
