David’s Crack / Davíðsgjá

Located near the meeting point of the Eurasian tectonic plate in Iceland’s Þingvellir Lake (Lake Thingvellir), this freshwater fissure is filled with crystal-clear glacial water and is a popular dive site. While not as widely known as Silfra, it holds significant appeal for local divers.

The access to the water is straightforward; you can enter directly from the lake shore. After a short, shallow swim, you'll find yourself within the long, narrow, and deep fissure itself. The maximum recorded depth of this underwater canyon is 21 meters. Visibility at Davíðsgjá can be exceptional, though it’s influenced more by weather conditions than in Silfra. Notably, the top of the fissure sits approximately 7 meters beneath the surface of Thingvallavatn lake, allowing for considerable immersion within the water. It's frequently observed that trout are drawn to explore this remarkable underwater environment alongside divers.

Much less people than Silfra with same awesome visibility, you can play in the underwater wonderland forever as long as you can stand the coldness.
