The high road or eastern road is a pass through the Mountains of the Moon to the Bloody Gate and on to the Eyrie in the Vale of Arryn. West of the Mountains of the Moon, the high road meets the inn at the crossroads in the Riverlands, where it connects with the river road running west and the kingsroad running north and south.
The road is wild and dangerous, climbing through rocky foothills and thick forests in the Mountains of the Moon, past high passes and deep chasms to the Vale of Arryn. Travelers on the road are often attacked by the mountain clans or shadowcats. It is often closed by snow. In parts the high road is just a stoney track.
The high road has seen much blood spilled throughout history.
An army five thousand strong led by Ser Robert Rowan was sent by the Iron Throne to restore order in the Vale of Arryn after the death of Lady Jeyne Arryn. Believing the Mountains of the Moon would be passable with the coming of spring, Robert's host took the high road to enter the Vale. On the march, the column struggled through deep snows and was attacked by mountain clans.
During the Great Spring Sickness, Lord Donnel Arryn ordered the Vale of Arryn sealed off, shutting down traffic from the high road and by sea, preventing the illness from spreading into the region.

Lysa: The gods have seen fit to proclaim him innocent, child. We have no choice but to free him. Guards. Take my lord of Lannister and his … creature here out of my sight. Escort them to the Bloody Gate and set them free. See that they have horses and supplies sufficient to reach the Trident, and make certain all their goods and weapons are returned to them. They shall need them on the high road.
Tyrion: The high road. As you command, my lady. I believe we know the way.
