Thingvellir (isl. Þingvellir) is a national park in a valley of the same name in southwestern Iceland. It is located near the Reykjanesskagi Peninsula, 45 km to the northeast of Reykjavik. In 2004, the national park was recognized by UNESCO as a World Heritage Site. There is a unique place close to the park, where divers come looking for new experiences. It is Lake Tingvallavatn with 3 islands of volcanic origin. The crystal-clear waters open up a mesmerizing world of fissures, cracks, and canyons that greatly differs from the ordinary marine and ocean fauna. It is also a tectonic fault zone — a border between the lithospheric plates of Europe and America.
Thingvellir is located not far from Reykjavik which has an airport. However, it specializes in flights from Greenland and the Faroe Islands and also accommodates domestic flights. If you arrive at Keflavik International Airport, you will have to get to Reykjavik and then take a bus to the park.
A subarctic marine climate dominates the region. In summers, the air warms up to +10 ˚C, while in winters, the temperature drops to ─1 ˚C. The weather is windy and unstable, with frequent drizzling rain. In the fissure, the water temperature is +1...+3 ˚С, while in Lake Tingvallavatn it reaches +2 ˚С.
Located at the intersection of tectonic plates, Silfra lava fissure is especially interesting for divers. It is famous for underwater tunnels and caves with water so clear that visibility can reach 300 meters. You can also touch Europe and America at the same time. The narrowest parts of the fissure allow you to do that easily.
