Ararat consists of two peaks, their summits about 7 miles (11 km) apart. Great Ararat, or Büyük Ağrı Dağı, which reaches an elevation of 16,945 feet (5,165 metres) above sea level, is the highest peak in Turkey. Little Ararat, or Küçük Ağrı Dağı, rises in a smooth, steep, nearly perfect cone to 12,782 feet (3,896 metres). Both Great and Little Ararat are the product of eruptive volcanic activity. Neither retains any evidence of a crater, but well-formed cones and fissures exist on their flanks. Towering some 14,000 feet (4,300 metres) above the adjoining plains, the snowcapped conical peak of the Great Ararat offers a majestic sight. The snowline varies with the season, retreating to 14,000 feet above sea level by the end of the summer. The only true glacier is found on the northern side of the Great Ararat, near its summit. The middle zone of Ararat, measuring from 5,000 to 11,500 feet (1,500 to 3,500 metres), is covered with good pasture grass and some juniper; there the local Kurdish population graze their sheep. Most of the Great Ararat is treeless, but Little Ararat has a few birch groves. Despite the abundant cover of snow, the Ararat area suffers from scarcity of water.

Ararat traditionally is associated with the mountain on which Noah's Ark came to rest at the end of the Flood. The name Ararat, as it appears in the Bible, is the Hebrew equivalent of Urardhu, or Urartu, the Assyro-Babylonian name of a kingdom that flourished between the Aras and the Upper Tigris rivers from the 9th to the 7th century BC. Ararat is sacred to the Armenians, who believe themselves to be the first race of humans to appear in the world after the Deluge. A Persian legend refers to the Ararat as the cradle of the human race. There was formerly a village on the slopes of the Ararat high above the Aras plain, at the spot where, according to local tradition, Noah built an altar and planted the first vineyard. Above the village Armenians built a monastery to commemorate St. Jacob, who is said to have tried repeatedly but failed to reach the summit of Great Ararat in search of the Ark. The village, the monastery of St. Jacob, and a nearby chapel of St. James were all totally destroyed by an earthquake and avalanche in 1840.

Local tradition maintained that the Ark still lay on the summit but that God had declared that no one should see it. In September 1829, Johann Jacob von Parrot, a German, made the first recorded successful ascent. Since then Ararat has been scaled by several explorers, some of whom claim to have sighted the remains of the Ark.
