We went to Georgia in September 2012. The trip was focused on mountains. During acclimatization we climbed Kazbek (5033 m n.p.m.) and some surrounding peaks (Sputuk, Ortsweri).Then, we went to Svanetia, for climbing on remote peak - Tetnuldii (4852 m n.p.m.). After that we went to Kachetia - famous wine region and Batumi - popular tourist destination at the Dead Sea shore.In Tbilisi we recommend staying in climatic polish guest house: http://whynothostels.com/tbilisi/tbilisi.html
