The hike along the lower canyon of the Jökulfall is approx. 7 Km and is an easy day hike. As opposed to the upper part, the canyon here is narrow, deep and sharp, with hidden waterfalls and interesting rock formations. At the lower opening there is a interesting theatre like landscape which has for years been the venue of a search for the Wholy Grail. A research made by a Italian gentleman with the name of Giancalo Gianazza indicates that the Wholy Grail was transferred to Iceland and hidden at this place.
