Driver and tour guide will pick you up from the hotel at 09:00 AM and will start hiking tour to Birtvisi castle. Birtvisi is ruined medieval fortress in Kvemo Kartli region of Georgia, which is a very small but a unique place with a strange shaped rocks. Easily passable canyons which are situated between these rocks represent a natural castle. Indeed, during the whole history this castle had a great importance for the feudalists.
