Today, we continue to cross the fields and hills from Quang Uyen to Ban Gioc waterfall after breakfast. Nestled among these amazing landscapes is the breathtaking Ban Gioc waterfall that stretches over 300 meters, bisecting Vietnam and China. We will have some time here to enjoy the great atmosphere around the falls, this is a great opportunity to take some great photos. Once you’ve finished at the falls, it’s time to head over to Nguom Ngao Cave, for a very different, but no less impressive natural wonder. The cave stretches for 2,144 meters underground and is brimming with incredible stalactites and stalagmites.

Breakfast at homestay then after a thirty-minute drive, you'll reach Tham Phay Cave, the hike starts with a steep uphill leading into the forest. Some rock at the top, and then a similar slope before the trail fades and you enter the valley. Turning west of the trail is a large patch of rock for you to find your way through, with the help and direction of your guide and safety team. The precarious entrance is at the end of the forest. Enjoy some snacks before starting to explore the cave.

Tham Phay Cave is a beautiful river cave with two underground river tributaries, where you will experience narrow passages, craggy mountains, and some deep pools with very nice photo opportunities. Plants and algae cover many calcite formations. Going deeper into the cave, you will find many unusual features of the cave such as the ceiling dome and many layers of rock, giving the walls a striking appearance. You will spend about five hours exploring this 5km deep river cave, which geologists have not discovered so far. Of course, we will provide you with the necessary equipment, such as helmets and powerful headlights. The cave expands considerably as you go through the original entrance and offers some great opportunities for excellent photos.
