Dive-site story
Submerged within Lake Thingvallavatn, Davíðsgjá is a volcanic fissure running directly from the rocky shoreline out into deeper water. Often regarded as the deeper, moodier sibling to Silfra, it offers sheer basalt fault walls and expansive underwater vistas. The dive begins with an entry into the lake shallows before navigating over submerged lava formations and descending into the dramatic geological rift.
