About Flosagjá Fissure

Flosagjá is located in Þingvellir National Park, accessible via marked walking paths from the main parking area. The fissure is narrow and deep, with steep rocky walls. Visitors can walk along the edge and peer into the clear water. The site offers excellent photo opportunities and a tangible connection to Iceland's unique geology. Flosagjá is less visited than nearby Silfra (the famous diving fissure), making it a quieter spot to appreciate Þingvellir's tectonic wonders.

Story & Folklore

Flosagjá is one of several dramatic fissures at Þingvellir created by the ongoing movement of tectonic plates. The plates drift apart by about 2 cm per year, slowly tearing Iceland apart. The water in Flosagjá is glacier-fed and incredibly clear.
