These two caves are in the Tu Lan cave systems and you cannot hike them by yourself because of their level of complexity. We have to go with a Oxalis professional guide/ porter to hike this. Anh and Andy are doing Hang Tien Cave Discovery (Code HT1) one of the days because this is the world's biggest cave and want to do that caving adventure. It is an all day 12 hour commitment.
For these caves, we can do 2 caves in 1 day with motorbikes or 16 seat van. Daily operation hours are: 7:30 AM to 4:30 PM
