If you’re up for another 1000m of ascent after climbing to the famous Tsminda Sameba Church above Kazbegi, this walk rewards with spectacular views, especially of Mt Kazbek. The path heads straight up the ridge behind the church. Allow up to eight hours from the church to the glacier and down again.
An alternative route, less panoramic but more protected on windy days, forks off to the left from the main ridge path after about 500m. The two paths meet again at the Saburtse Pass at about 3000m altitude. From here you descend slightly to cross a small river before ascending to the side of the Gergeti (Ortsveri) Glacier. Stream water is normally OK to drink beyond the pass as there are no animals up here.
