I recommend these excellent maps:
Georgien World Mapping Project 1:350,000 Reise Know-How Series. This large map is made of tear-resistant paper and has more detail and clarity than any other single map I’ve found. My favourite for travelling. The Georgian National Tourism Administration produces excellent regional maps available free from their offices. One side is tourist information about the best sites; the other is a 1:200,000 scale map of each region, with the sites marked. Collect the whole series.
