Kirkjubæjarstofa

Foss á Síðu is the name of an old farm, approximately 10 km east of Kirkjubæjarklaustur. A beautiful waterfall cascades over the cliffs above the farm, which flows from Lake Þórutjörn. This magnificent spectacle catches the eye of everyone that passes by. An easy hiking trail leads up to Lake Þórutjörn where the view over Síða is amazing.

Dverghamrar (Dwarf Rocks), just east of Foss, are peculiar and beautiful formations of columnar basalt. On top of the columns there is cube-jointed basalt. The landscape is thought to have been moulded at the end of the Ice Age. The sea level was higher at that time and it is believed that the waves caused the peculiar look of the rocks. Dverghamrar are a protected natural monument. Columnar basalt is formed when lava flow gets cooled and contraction forces build up. Cracks then form horizontally and the extensive fracture network that develops results in the six sided formation of the columns.

Kirkjugólf or 'the church floor' is an 80 square meter expanse of columnar basalt stone slabs which have slowly eroded during the time when sea covered the area. The hexagonal 'tiles' look every bit as if they were man-made flooring but there has never been a church or any other building on the site. The protected natural monument is located just a few hundred meters east of the village of Kirkjubæjarklaustur.

Fagrifoss is a scenic 80 m high waterfall in Geirlandsá River. Basaltic pillows occur in the vicinity of the waterfall which cascades from 140m thick hyaloclastite deposits. Fagrifoss is situated on the F206 road to Laki craters, a rugged road with rivers that can be treacherous to cross if the water level rises due to rain and thaw. A 4x4 vehicle is needed and the area is only accessible during summer.

Fjaðrárgljúfur is a magnificent and massive canyon, about 100 meters deep and about two kilometres long. The canyon has sheer walls, and is somewhat serpentine and narrow. The bedrock in Fjaðrárgljúfur is mostly palagonite from cold periods of the Ice Age and is thought to be about two million years old. The river Fjaðrá has its source in the mountain Geirlandshraun and falls off the heath edge in this stunning canyon until it makes it down into Skaftá river. Fjaðrá has changed a lot in the course of time. Today Fjaðrá is often rather low in water and therefore hikers can safely choose to walk inside the canyon. However, wading is necessary fairly often. Deep in the canyon there are waterfalls so one needs to walk the same way back. Most people choose to walk along a walking path up on the canyon's edge while simultaneously enjoying the view above the canyon.

Formation of the Fjaðrárgljúfur canyon

It is believed that Fjaðrárgljúfur formed at the end of the last Ice Age, about nine thousand years ago. When the glacier retreated, a lake formed in the valley behind a hard resistant rock. The run-off from the lake flowed to where Fjaðrárgljúfur is today. Glacial rivers from the glacier's edge carried a lot of sediment into the lake and the river which ran from it dug itself down into the rock and down onto the palagonite in front of it. Because the cascade has been so large, it was powerful in digging out the canyon. Eventually the lake filled with sediments and the river's strength dwindled. When the lake filled up completely, the river began to dig itself into the sediment layers which it had previously left in the valley. Fluvial terraces on both sides in the valley give an indication about the original height and location of the lake while a deep channel in the palagonite serves as a silent reminder to the power of nature.
