The Gjáin Waterfalls merely pertain to the pair of falls within the lush garden paradise at the rift zone about a half-hour's walk from the historical farm Stöng in Ţjórsádalur. There are actually two ways to access Gjáin. One is by doing the walk from Stöng while the other is along a fairly rough unpaved road that connects Stöng with the Háifoss turnoff. We took the latter path though you can get frontal views of the leftmost waterfall (as opposed to the rightmost one as pictured above) with the former path.
