Possibly the most misterious region in the Greater Caucasus. It borders with Chechnya in the north, with a little more than 3000 inhabitants, who some believe are the last descendants of the Crusaders. Through Khevsureti run steep valleys overlooked by ancient fortresses.
The village of Shatili, a mere 6 km from the Chechnyan border, lies on the river Argun. It's a UNESCO WOrld Heritage site, with 60 towers that make this village look like a fortress.
Mutso, 1900 m a.s.l. is a medieval village built in an almost inaccessible position that will remind some of the famous Macchu Picchu, the lost city of the Inca in Peru.
Together with Tusheti, Khevsureti is easily the most inaccessible part of Georgia. The road to Shatili is closed for many months every year due to snowfall and it's only open to 4wd vehicles since May to October.
Departing from Shatili, a long trekking route leads to Tusheti, crossing the Atsunta Pass and the Tebulo Range.
