Our first stop will be Thingvellir, a national park recognized by UNESCO. From the park, we marveled at the breathtaking expanse of Þingvallavatn, the largest lake in the country. Walking amidst the park, we traversed the remarkable boundary between the European and American continental plates. We also witnessed the historic gathering place of the Althing, the world's oldest parliament, and gazed into Silfra, a symbolic fissure renowned for its crystal-clear waters, drawing divers from all around.
