Thien Duong or Paradise cave located 60kkm from Dong Hoi City, Quang Binh province in the central part of Vietnam. Discovered in 2005 by a local man and later explored by the British cave explorers, Paradise cave is listed as the world's longest cave (more than 30km) with beautiful and unique stalactites and stalagmites. Vietnam has so many nice caves such as "Cave of surprise", Thien Cung grottoes in Halong Bay, Trang Ang caves, Tam Coc caves in Ninh Binh, Nguom Ngao cave in Cao Bang, Phong Nha cave in Quang Binh, but Paradise cave is the nicest one that must be visited on a holiday in Vietnam. Let's explore the cave with Vivutravel and book a tour to Paradise with us.
