Thingvellir Almannagja and Oxararfoss Walk

This short walk in Thingvellir National Park leads through the Almannagja rift wall to the Oxararfoss waterfall, on the site where Iceland's medieval parliament, the Althing, first met in 930. The park lies about 50 km and 45-50 minutes by car east of Reykjavik, near Selfoss, and is part of the Golden Circle route, so scheduled tour buses stop here. Car parking carries a fee of roughly ISK 1,000 (about $8). The walk covers about 2-3 km return with an elevation change of around 60 m and takes 1-1.5 hours, which places it in the easy category. The path starts near the upper viewpoint and descends through Almannagja, a canyon formed by the pulling apart of the North American and Eurasian tectonic plates, with high basalt walls on one side. The surface is a mix of gravel, packed dirt and stone steps, with some boardwalk and stairs near the lower end. Key landmarks include the Logberg, or Law Rock, area where law-speakers once recited the laws, the flag pole marking the traditional assembly site, and the Oxara river, which drops into a pool at Oxararfoss. Turn-around points are easy to choose along the path, though most visitors continue to the waterfall before returning. The lower part is partly shaded by the rift walls, but the plain is exposed to wind. Information boards and a visitor centre provide history and facilities, including toilets and a cafe. Drinking water is available at the visitor centre, but not on the path. Walking shoes and layers are enough in summer, and ice cleats are advisable in winter when the steps and paths can be icy. The park is open year-round, with May to October offering the easiest conditions, and its UNESCO World Heritage status makes it a cultural as well as a scenic stop.
