Íráfoss (sometimes also known as Arjanurfoss) is a beautiful, 41-meter-high waterfall on the Írá River, which originates from the Eyjafjallajökull glacier. It is one of the few picturesque waterfalls in southern Iceland where you are very unlikely to encounter anyone. Despite being so close, the waterfall is relatively inaccessible due to the rugged terrain surrounding it. There is a rock wall in front of the waterfall, making easy access impossible.
Íráfoss means Irish Waterfall, and it was named in honor of a former resident of this area. However, there is no direct evidence to support this; it is merely a legend.
You can find Íráfoss between Hvolsvöllur and Vík í Mýrdal, near the small local road number 246 – Skálavegur.
There is a small parking lot near the waterfall, and from there, Íráfoss is about 100 meters away.
