Gjáin, "The Gorge" is a picturesque appealing , gorge like depression with flowers and ferns, meandering streams and a fine waterfall at its upper end, - a miniature landscape like an Oriental rock garden with a breathtaking scenery all around. Gjáin is located in the Ţjórsárdalur Valley and the river Rauđá runs through it with many pretty waterfalls. The vegetation in Gjáin differs very much from its surroundings that are rather barren, but Gjáin is well sheltered from wind and therefore the rich vegetation. However, the vegetation is fragile and visitors are urged not to walk outside of the marked trails. There is a rather steep trail down into Gjáin with loose gravel and visitors need to be careful and watch their steps. Many people that have never been to Iceland may still be familiar with the beautiful landscape at Gjáin, but the Water Dance scene of the famous Game of Thrones was filmed at Gjáin Gorge.
