Phong Nha-Ke Bang National Park was a recognized UNESCO World Heritage Site in 1993. Paradise Cave is one of the most beautiful Caves in Phong Nha. However, it's an incredible home to the 360-million-years-old rock formations, the 31km long, the longest and the most beautiful in Asia. The countryside and surroundings in Phong Nha are fantastic with some colonist buildings ring by limestone mountain ranges, lush foothill farms, rice paddies, rivers, and tiny villages make it more rustic and spectacular. We have a full-day guided tour to explore the most beautiful Caves of Paradise with 3 hours to discover so many places inside. Next is the Dark cave with combined adventures;  zipline to Dark cave, enjoy mud bathing, swimming, and kayaking. Finally, we return to Phong Nha town on Ho Chi Minh road, through mountain ranges, valleys, and tropical rainforests. Dine with the team and stay one more night in the town.
