On the final day of your trip, indulge in some relaxation and rejuvenation at the hot springs in Ba Vi National Park. The park is known for its natural hot springs, which are believed to have therapeutic properties. Take a dip in the warm mineral-rich waters and let your worries melt away. Afterward, you can enjoy a soothing massage or spa treatment to further enhance your relaxation experience. If you still have some energy left, you can explore the nearby Tien Sa Waterfall and enjoy the tranquil atmosphere. In the evening, bid farewell to Ba Vi National Park and head back to Hanoi, feeling refreshed and rejuvenated.
