The first place where you will stop is a shop to buy snacks. Since the area doesn't have good restaurants and we do not have a lunch stop, you should get some snacks not to feel too hungry and uncomfortable.
And next, we go to a salty lake, where we have an outstanding possibility to take some nice pictures. The lake is on the way to David Gareji Lavra, and the views are astonishing for taking memorable photos.
In total, for the shop and the lake, we will have 30 minutes.
