The Azat (Armenian: Ազատ) is a river in the Kotayk Province of Armenia. Its source is on the western slope of the Geghama mountains.
The Azat River is known in Armenia for its beauty. It flows for 55 kilometers, the valley occupies 572 square kilometers. The Azat passes through the Khosrov State Reserve. In its lower reaches, the river flows into the Ararat valley. The Azat is known for its numerous spectacular waterfalls and its rock choked river bed.
One section of the Azat, where it meets River Goght, is particularly fascinating. It is a canyon known as Canyon of Garni. The canyon's formation is so unique that it almost looks artificial. The canyon is composed of regular hexagonal prisms. Near its end, the gorge's beautiful formation has prompted the name Symphony of Stones.
