Birtvisi canyon
Southwards from Tbilisi, there is a unique area of 4 sq.km. which is traced with small gorges. In the past rivers flew in all those small gorges, which during hundreds of milleniums managed to cut the cooled lava and as a result formed rock prominences of dozen meters height. Today these rock prominences are dislocated in line, in succession or joined to each other and they form small narrow canyons.
I offer one and two day tours to Birtvisi canyon. One day tour includes hiking to Birtvisi fortress, and two day tour is for those who likes extreme.
