Davíðsgjá, like Silfra, is a fissure located in Lake Thingvellir. Davíðsgjá is not as famous as Silfra, but it is a favourite among local divers. At Davíðsgjá you can walk straight into the water and after a nice shallow swim in water that is usually warmer than Silfra, you will enter the long, deep and narrow 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. The top of 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.
