Davidsgja
Davidsgja is located near the Eurasian tectonic plate, approximately 7 kilometers on the other side of the continental rift zone. The underwater topography in Davidsgja is breathtaking; it's difficult to comprehend the incredible size, monstrous scale, and origins of the massive round boulders and square slabs stacked on top of each other. This is accentuated by the water's incredible visibility, which makes everything so wonderfully clear. Dwarf char fish, a shy freshwater fish, hide in the lava. Giant trout from deep within the lake will occasionally enter the shallows to explore.
The best times to dive are in the summer when the winds are low and after spring when the lake's winter ice has melted. Diving along, surrounded on both sides by solid volcanic rocks, there's a sense of awe, of geological grandeur, as if you were discovering a new city for the first time. Few dive sites in Greenland have such stunning natural architecture, let alone the space and freedom to explore it.
