Greater Ararat is 5,137 metres tall - that's more than five kilometres straight up, taller than Mont Blanc in the Alps. Little Ararat next door is 3,896 metres tall. Together they look a bit like a big lion sitting next to a smaller cub.
The mountain is a 'stratovolcano', which is a tall cone-shaped volcano made of layers of old lava. It hasn't erupted for thousands of years and is fast asleep today, with its summit covered in a thick cap of snow that almost never melts.
From the Armenian capital Yerevan, on a clear morning, Ararat fills the whole southern sky. Photographers in Yerevan say there is a 'good Ararat day' when the air is so clear you can count every ridge. On other days, clouds wrap around it and only the tip pokes through.
Ararat appears on Armenia's official coat of arms - the symbol you'll see on Armenian passports and government buildings. It is one of the few national symbols in the world that shows a mountain in a neighbouring country, because for Armenians the mountain is part of their landscape whether the border is on this side or that.
