Tsana has been mistaken for the alpine camp Zeskho, so if you and your tour guide are heading towards Zeskho you will pass Tsana (on your right) The road through the gorge is incredibly difficult to travel, even with a very good 4 x 4, but if you make it to Tsana, the road gets a little easier. Tsana will be the first major human presence you will see once you pass Ushguli. It is about one hour further past Tsana for the turnoff to Zeskho.
