A UNESCO World Heritage Site, Thingvellir National Park is a historically and geologically significant location. It is one of the few places in the world where the North American and Eurasian tectonic plates are visibly drifting apart, forming a striking rift valley. Additionally, it is the site of Althing, Iceland’s parliament, founded in 930 AD, making it one of the world’s oldest parliamentary institutions. Visitors can walk through scenic trails and witness the dramatic geological formations shaped by millennia of tectonic movement.
