Cold water and sky-leaning cliffs open as you step onto the lava-etched shore of Silfra. The fissure’s water is glass-clear, daring you into a weightless corridor that threads the gap between the North American and Eurasian tectonic plates. Guides fit you into a drysuit or freedive wetsuit, check gear, and walk you to the edge; below, the rifts and ridges of ancient volcanic rock rise like underwater architecture.
