In the morning explore the Rabati fortress. The old stone Rabat fortress, the main sight of the Akhaltsikhe town, stands on the small hill on the very shores of the Potskhovi River. Its name means “fortified place” from Arabic. Drive to Vardzia. En route, short stop at Khertvisi Fortress, one of the strategic citadels on the Silk Road built in the 10th century. Arrive to Vardzia, which was erected in the 12-13th centuries during the rule of George III and his daughter Queen Tamara to protect southern boundaries of Georgia. Unlike majority of sights with random rooms cut in rocks,Vardzia is a multi-storied complex with streets, tunnels and stairs leading to monasteries, temples, fortresses, baths, libraries dwelling houses and so forth. Drive to Akhaltsikhe for overnight.
