Foss á Síðu (Waterfall at Síða) is a farm right on the Ring Road in Iceland in the Southern Region approximately 10 kilometers east of the small village Kirkjubæjarklaustr. It is noticeable because of its spectacular surroundings and the small waterfall falling from the beautiful cliffs lightly covered with moss vegetation. A work of art with nature's hand.
The farm is mentioned in the Book of Settlement and has thus been here since Iceland times of settlement, in the 9th century. Placed in front of beautiful cliffs with its stunning small waterfall it is hard to pass by without noticing. The farm takes its name after the waterfall that comes from a lake, Þórutjörn, on the top of the cliffs. The cliffs are accessible at a steep walking path right by the waterfall and is worth walking. From the top, the view is spectacular. Although the waterfall doesn't have a lot of water, it is one of the most photographed waterfalls in Iceland.
Sometimes the waterfall is blown away by heavy winds when a limited amount of water is coming from the lake.
According to a local folklore story, a rare kind of ghost wanders around the area around the farm Foss and the nearby farm Hörgsland. The ghost is a dog who's name is Móri, or simply Ghost, who carries with him a curse that was directed at a particular family in the 16th century. The curse was set out to last for nine generations. There are those that argue that the curse has finished its course, and Móri has disappeared forever, but not all. Throughout the centuries, Móri has never done any harm to people outside this unfortunate family.
