Fodor's Expert Review Hljóðaklettar

The "Echo Cliffs" is an extraordinary labyrinth of rock formations, located on the west side of Jökulsárgjúfur canyon off Route 862. There are two trails from the parking lot to this remarkable attraction: one is a short (1 km) there-and-back path leading to a magnificent rock named The Troll, and another longer trail (3 km [1.85 miles]) takes a ring around the areas and is more challenging. The name of the attraction comes from the honeycomb textures of the rocks, which act as sound processors amplifying the reverberating sound of the river.
