Hang Va – Bí ẩn những tháp đá kỳ lạ dưới lòng đất Quảng Bình I Khám Phá Cuộc Sống Mỗi Ngày I

Hang Va is a unique cave located near Son Doong in Phong Nha-Ke Bang, famous for its surreal \"Tower Cones\"—hundreds of cone-shaped calcite structures rising from underground lakes. Discovered in 1992 and surveyed in 2012, the cave features a complex system of water, waterfalls, and geological mysteries that suggest a vast, interconnected underground network.
