Hjálparfoss is a beautiful, two-stepped waterfall located in the Þjórsárdalur valley in South Iceland, about 30 kilometers (19 miles) from the town of Flúðir and roughly 120 kilometers southeast of Reykjavík. It lies where the rivers Fossá and Þjórsá converge, with Fossá cascading down split basalt columns into a tranquil pool before merging with the larger Þjórsá river, Iceland’s longest river.
The name Hjálparfoss translates to “Help Falls,” a reference to the area's historical significance. Travelers crossing Iceland’s harsh and desolate highlands via the Sprengisandur route found this lush valley a much-needed respite, where ample grass and water provided vital “help” for their horses after difficult journeys. Surrounding the waterfall is a striking landscape of volcanic lava fields formed by eruptions from the nearby Hekla volcano, which earned a medieval reputation as the “Gateway to Hell” for its explosive nature.
Hjálparfoss is set among unique basalt rock formations that frame its twin cascades elegantly. The waterfall drops about 9 meters (30 feet) and spans roughly 27 meters (89 feet) in width. The area downstream is home to Iceland’s second-largest hydroelectric power station, Búrfellsstöð, which utilizes the waters from these rivers.
