Curved hexagonal basalt columns of the Symphony of the Stones in Garni Gorge, Armenia

A cliff of hexagonal basalt columns hanging over the Azat River, curved like organ pipes, a short scramble below one of Armenia's most visited temples.

The Garni Gorge cuts 100 m into the volcanic plateau east of Yerevan. Along the Azat River the walls are made of columnar basalt: five- and six-sided prisms formed when a thick lava flow cooled slowly and contracted into regular joints. The columns here are unusual for two reasons. They are long, some over 50 m, and they curve, fanning out from the cliff face in arcs that give the formation its name.

The best section is a 500 m stretch just downstream of the medieval bridge, where the columns overhang the path.

Why it stays quiet

Almost everyone who comes to Garni stops at the Hellenistic temple on the rim and leaves. The gorge floor needs either a rough 4x4 track or a steep 30-minute walk, so on weekday mornings the path is usually empty.

Before you go

The temple charges an entry fee; the gorge does not. Wear proper shoes: loose basalt scree. Avoid after heavy rain (rockfall).
