Scuba centers on the striking Silfra freshwater fissure in Thingvellir National Park. The water is cold throughout the year and demands excellent drysuit buoyancy control. Operators also describe Davidsgja in Lake Thingvallavatn, geothermal Kleifarvatn, the kelp habitat at Gardur and the brackish Bjarnagja fissure, but excursions outside Silfra are conditional rather than guaranteed. Park rules / DIVE.IS site directory.
Silfra
The headline guided open-water fissure dive, with park-regulated depth and drysuit prerequisites.
Davidsgja
A second permitted national-park fissure with a lake approach and weather-sensitive visibility.
Lake Kleifarvatn
Seasonal geothermal lake dives, subject to water levels, route restrictions and volcanic conditions.
Gardur
A marine shore/pier dive with kelp forests, algae and fish.
Bjarnagja
Reykjanes lava fissure near Grindavik; overhead sections described by operator are a distinct specialty hazard, not an ordinary open-water entitlement.
