Svaneti is a high mountain region in northwest Georgia, enclosed by the Greater Caucasus Range on the north and the Enguri and Rioni river valleys to the south and west. It is the homeland of the Svans — a people who speak a distinct Kartvelian language and maintained a degree of independence from every empire that nominally controlled Georgia, simply because the mountains made the region nearly impossible to conquer or fully administer. The result is a landscape that looks almost medieval: stone defensive towers still bristle from every village, churches hold frescoes and icons that have not moved since the 12th century, and the hamlets perch on hillsides above alpine meadows as if the 20th century arrived late and left early.
The two main areas for visitors are the Mestia valley — centred on the regional capital of Mestia — and the upper Enguri valley, which leads to Ushguli, a group of four villages at 2,100 metres that claim to be the highest continuously inhabited settlement in Europe. The road between Mestia and Ushguli takes about three hours by 4WD in summer; the Enguri valley can also be walked in two to three days along the classic Mestia-to-Ushguli hiking route. The route passes through the villages of Zhabeshi, Adishi, and Iprari, each with its own cluster of towers, and crosses two high passes.
Mestia has developed rapidly since the late 2000s: a new airport opened in 2010, the roads were improved, and the town now has guesthouses, restaurants, and a reasonable ski area at Hatsvali. The atmosphere remains fairly rough-and-ready, with cattle sharing the unpaved streets and the towers still occupied. Svaneti museums hold some of the finest medieval goldsmithing and icon painting in Georgia — much of it evacuated here from lowland churches during the Mongol invasions of the 13th century and never returned.
This is serious mountain country. The Caucasus peaks above Mestia — Tetnuldi (4,858 m), Ushba (4,710 m), and the Bezengi Wall of 5,000-metre peaks on the Georgian-Russian border — are among the most demanding climbs in the range. The weather is unpredictable, the roads are difficult, and the infrastructure outside Mestia is basic. Go for that reason.
