This whole part of the world is known for its hospitality, and the parts of Southern Armenia which see few tourists are even more so than others. Venture into a village for directions, and you can find yourself at the receiving end of a feast, homemade fruit oghi vodka being drunk and them making you spend the night. Refusing hospitality is often challenging, but don't bother as the experiences are sure to be memorable.
There is one main highway going through this region, which leads to Iran at the southern end. You'll see Iranian trucks coming and going, as well as a decent number of barbecue restaurants along the highway.
