Last summer I had an amazing solo weekend to the remote Tusheti region in the northeast, bordering to Dagestan (Russia). First up through the 2927m Koja pass and then down winding roads on the other side. These roads open at the end of June and close in September-October, nevertheless, a couple of handful of people live there all year round in deep isolation.
The views are absolutely breathtaking. Travelling on my own I made sure to stop and talk to people I passed on the way. Good, honest, beautiful people!
To get there you’ll need a 4×4 – in Telavi you can find people to take you. It’s easy to find homestays once you get there.
