Þingvellir National Park is not just any old park - it's where the cool kids of Iceland used to hang out back in the day! From 930 to 1798, this place was buzzing with the Althing, an open-air assembly where free folks gathered to set laws and settle disputes. It was like a giant outdoor parliament party where history was made and legends were born. The park is like a time machine, showing off ancient turf and stone booths where all the action took place. While the entrance to the park is free. There is a parking fee.
