Þingvellir National Park, where the Icelandic parliament was established in the year 930, is the most historic landmark in Iceland. Geologically speaking, Þingvellir is also of great importance because the mid-Atlantic ridge runs right through Þingvellir creating a fascinating rift valley where the two continental plates are gliding apart at a rate of approximately one to two centimetres per year. Þingvellir is a natural paradise with lunar-like landscapes where you can find Iceland´s largest lake, Þingvallavatn. The park includes an information centre with a café/restaurant and a camping site.
