Does anyone have any information about travel in this country?
What type of information are you looking for?
We were there about 4 years ago - easy enough to get around. We just went with taxis even for long distances as there were 4 of us.
It would help if you have more specific questions to understand what type of information you are looking for.
Check out the Lonely Planet Armenia guidebook for planning a trip. You'll find general travel info as well as tour, hotel, restaurant, sightseeing recommendations and more. You can also get info from the Armenian tourist board, here's one tourism site: http://www.tourismarmenia.org/#axzz3F1eNrcI1
