Morning: Tan Hoa - Hang Tien 1

07:30 - 08:00 AM Pick up and one-hour drive on Day 1 to the Oxalis Adventure office in Tan Hoa, located 70km from Phong Nha. Briefing and tour preparations are here.

The trek starts off with a steep uphill section, leading into the jungle. Some rocky sections at the top, and then a similarly steep descent before the trail levels off and you enter the valley. Turning west the trail is a large jumble of rocks to pick your way over, with the help and direction of the guide and safety team. The huge entrance is at the head of the valley. Enjoy some snacks before starting the cave exploration. As you enter the cave you will appreciate the full size of the passage. Plants and algae cover many of the calcite formations. Further into the cave you will see many unusual cave features such as a ceiling dome, and multiple layers of rock, giving the walls a stripy appearance.

Afternoon: Tan Hoa - Phong Nha

Retrace the journey back to the entrance down the rocky valley and stop for lunch and a swim in the beautiful natural spring. Refreshed, it’s then time for the big hill back up and down to the road for the pickup and return to the office for a shower. Transfer to Phong Nha arriving at around 07:00 PM.
