Azerbaijan is not one of the best travel destinations, but could be worth a visit for some special experiences.
Nomadic Matt has provided an itinerary that could be worth reading.
According to Wikipedia, "Azerbaijan, officially the Republic of Azerbaijan, is a transcontinental country located at the boundary of Eastern Europe and Western Asia. It is a part of the South Caucasus region, and is bounded by the Caspian Sea to the east, Russia (Republic of Dagestan) to the north, Georgia to the northwest, Armenia and Turkey to the west, and Iran to the south. Baku is the capital and largest city."
Here we quote the best way to travel in Azerbaijan provided by Nomadic Matt, a New York Times best-selling author of How to Travel the World on $50 a Day and Ten Years a Nomad, as well as the founder of his website.
