You can get out of Southern Armenia by heading up to Central Armenia, heading east to Karabakh, or heading south to Iran. Again, buses and vans marshutnis heading north to central Armenia and south to Iran are fairly frequent. Some buses go all the way to Tehran. From Goris and points north, vans or taxis can be caught to Karabakh, and taxis to Yerevan can be caught from anywhere in the South, though going to a bus station might yield some fellow passengers to split a ride with.
