Sanatorium Arzni

Arzni Sanatorium in the Kotayk Province of Armenia, in the Hrazdan River gorge north of Yerevan, is one of the South Caucasus's most established mineral water resorts, drawing from chloride and bicarbonate-rich springs whose natural carbonation and mineral composition were studied extensively during the Soviet period when Arzni was developed as a major health resort serving the Armenian SSR's population. The naturally carbonated mineral water of Arzni, part of a long thermal tradition maintained at the sanatorium complex, flows from geological formations in the basaltic geology of the Kotayk highlands in a gorge setting of considerable scenic drama, where the Hrazdan River's ancient course through volcanic rock provides both natural beauty and the geochemical environment supporting the springs' specific mineral character. The proximity to Yerevan, the extraordinary Kotayk monastic heritage including Geghard and Khor Virap visible on the horizon, and the cool mountain climate of the Hrazdan gorge make Arzni an important component of Armenia's spa and wellness tourism offering.
