The Longoza Nature Reserve covers an area of 842 hectares on the low banks of the Kamchia River as it flows into the Black Sea 30 km south of Varna. It is not a usual forest as creepers some of which up to 50 metres long form a green “curtain” that is difficult to pass through. High century-old trees stoop over the river. Sunshine seeping through the branches creates a strange feeling of mystery. What you see there will remind you of a tropical forest. In fact this is the last representative of a longoz (swamp forest) in Europe.
