Gjáin is a hidden gem tucked away in Þjórsárdalur valley in South-Iceland. It's a breathtakingly beautiful place that feels like a fairyland with its waterfalls, lush vegetation, and unique lava formations. The main river, Rauðá, runs through here, creating stunning cascades like Gjárfoss. This oasis has become even more popular since it was featured in Game of Thrones, but let's remember to treat it with respect and preserve its delicate beauty for future visitors to enjoy.
