Fly into Tbilisi or Kutaisi, whatever is more convenient for you. Then, a car will take you from any of these cities to the town of Oni in the Racha-Lechkumi region. The ride takes around 7 hours from Tbilisi and 3 hours from Kutaisi.
When you arrive at Oni, check into a cozy family-run guesthouse. Leave your things in your twin room, enjoy a traditional Georgian meal, and tuck in.
