There are actually many places you label as an oasis in Iceland and Gjáin is most definitely on of the most beautiful. One of the fascinating factors is the size. Gjáin is a tiny valley with small picturesque waterfalls, clear, tranquil ponds and amazing delicate volcanic structures it is like a sample of the Icelandic nature. For visitors, it is almost surprising as it appears like from nowhere and only visible as you approach the edge of the tiny valley. Even the lava in this area takes on beautiful form in Gjáin. You will find lava caves and a lot of basalt column as well as volcanic tuft.
A place to visit in summer
It is a beautiful place to visit but only from the beginning of June until the beginning of October. Outside that time of year, it is either not accessible and filled with snow or simply not interesting due to dull colors and early spring water. In summer, on the other hand, the small valley is covered with lush green grass and vegetation. It is believed to have been the riverbed of the river Þjórsá in earlier days. Nowadays, it is Rauðá (the Red River) running through the valley, beautifully framed by stunning rock formations, displaying its beautiful waterfall, Gjárfoss.
