Kazbek is a dormant volcano with an ice-filled crater. From the south, the mountain appears as a perfectly symmetrical white dome rising above green ridges. The Gergeti Glacier descends from the summit to roughly 3,000 m – its tongue is visible from Stepantsminda. At 3,800 m, carved into the rock, lies the Betlemi (Bethlehem) cave monastery, mentioned in medieval Georgian chronicles as a repository for church treasures. The cave entrance sits atop an 80 m rock face, accessible via an iron ladder.
The climbing route begins from Gergeti Church (2,170 m) and passes through the intermediate Deka Camp (3,020 m) to base camp at Betlemi Hut (3,653 m). The hut is a stone building with bunk beds for 20–30 people. Conditions are basic: sleeping bags required, outdoor toilet. From here, acclimatization hikes reach 4,000–4,100 m. Summit day starts at 2–3 AM: up the glacier to a plateau (4,500 m), then a 30-degree slope to the saddle (4,900 m), and a final 100 vertical metres of ice at up to 40–45 degrees.
For those not planning a summit attempt, day hikes are available: to the Gergeti Glacier tongue (~3,000 m, 3–4 hours round trip) or to Deka Camp with views of icefalls and Kazbek's wall. These routes require no technical gear – just proper trekking boots.
