Svaneti is an absolute must! It offers some of the most spectacular and dramatic landscapes imaginable - together with a mysterious and unique culture. I highly recommend a visit to Ushguli, probably Europe's highest village (take warm clothing). It feels like a Caucasian version of Middle Earth. Only a small part of the village, called Chazhashi, is actually part of the WH list but the whole area is breathtakingly beautiful and historically interesting. Unfortunately, as of 2013, there are no scheduled flights to/from Mestia! Except from expensive charter flights (in Cessna, from Natakhtari Airfield north of Tbilisi), the only way of public transport is by minibus. The road between Zugdidi and Mestia is in good condition, Mestia-Ushguli is being upgraded these days. However, travel time is still very long and may require transfer: Tbilisi-Mestia approx. 10-12 hours by minibus, Kutaisi-Mestia 5-6 hours, Zugdidi-Mestia 3-4 hours; Mestia-Ushguli was a whopping 3 hours for 48 km in 2013.
