Waters from Eyjafjallajokull’s melting ice flow into the Seljalands River and into the sea but, before making the final leg of this journey, the waters pass over a high cliff forming the spectacular Seljalandsfoss Waterfall (foss means waterfall in Icelandic).The waterfall has a single clear drop of 60 m into a calm pool below set in a flat area of meadowland. The pathway to the waterfall actually leads directly behind the waterfall making it one of the few in the world that it is possible to walk behind. The area behind the waterfall also features a small cave.

Gígjökull glacier Next, we will continue our way in the direction of Thorsmork and head all the way up to Gígjökull, one of the outlet glaciers of the Eyjafjallajökull volcano. You can walk entirely to the icefall edge, touch and walk on the glacier. You can get an idea of the forces that were at play during the 2010 eruption of Eyjafjallajokull that not only destroyed the agricultural region around it but stopped air traffic in Europe. Powerful glacial bursts emerged from Gigjokull during the eruption, sending meltwater gushing down and flooding the surrounding landscape. You’ll witness that the impact of the eruption is still very visible in the area.

The Skógafoss is one of the biggest waterfalls in the country, with a width of 25 metres (82 feet) and a drop of 60 m (200 ft). Due to the amount of spray the waterfall consistently produces, a single or double rainbow is normally visible on sunny days.

Reynisfjara is a famous black sand beach on Iceland's southern coast, known for its striking black sand, basalt columns, and the Reynisdrangar sea stacks. The beach is characterized by its powerful North Atlantic waves and a cave called Hálsanefshellir. Visitors should exercise caution due to the unpredictable ocean conditions.
