I haven't, I arrived here yesterday around 5pm. But I looked up Mestia. I'd say it looks like a more populated version of where I am now. But I'm more in the south near the Armenian border still. A very small village. There's no tourism to an area like this. As I type this from my phone, I look outside the kitchen to a vast nothingness with huge mountains in the distance. Haven't seen anything like this before. I can see why people here enjoy the traditional life.
I'll be making some posts about it at some point, there's a lot to share about it all!
Sounds cool!
The mountains are what makes Mestia special, I posted some of my photos here: https://travelfeed.com/destinations/georgia
Chiatura is also a cool place to visit if you're into urbex and cable cars.
