The Phong Nha National Park is located in the central west of Ho Chi Minh trails close to Laos, and it is home to a rich diversity of flora and fauna. Phong Nha caves were recognized as a UNESCO World Heritage Site in 1993. Son Doong cave is one of the world's largest natural caves. Located near Laos–Vietnam border, Son Doong has an internal, fast-flowing underground river and the most significant cross-section of any cave worldwide.  However, Paradise Cave is one of the most beautiful Caves in Phong Nha for travellers to explore with a day trip. 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 central province of Quang Binh. The countryside and surroundings in Phong Nha are fantastic. The small town and it's surroundings have 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, Dark with zipline adventures to mud bathing, swimming. After breakfast, we travel by bus on Ho Chi Minh road to Paradise Cave, spend 3 hours exploring this cave, and travel by bus to a restaurant for lunch. After we take zip line cable to Dark Cave, then take mud bathing and enjoy swimming. 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 city.
