This is a starting point, not a fixed package. Route, length, pace and price are always set for you.
The idea
Ten days is enough for five bases at a slow pace: two nights in most places so you unpack less and see more. The sequence runs east to west, so the mountains come first and the sea comes last.
How the days might flow
Spend the first two nights in Tbilisi, including the old city and a trip to Mtskheta. Then drive north along the Georgian Military Highway to Kazbegi for two nights: Gergeti Trinity Church beneath Mount Kazbek, and an easy second day on a quieter mountain road.
Come back down to Kakheti for two nights of vineyards and a proper lunch with a winemaker. Cross the country to Kutaisi for Gelati and the caves and canyons, and finish at the Black Sea in Batumi.
What Rezo adjusts
Everything. Add a week in the mountains, drop the sea, spend a night in Svaneti, or ask for a slower day. He also decides the order for the season: see the seasons guide.
