All tours require walking, so prepare comfortable trainers or sandals. Prepare for the weather appropriately and bring hats, sunscreen, rain gear etc. The Dark cave does not require shoes, but be sure to bring your bathers and your own towel. We recommend that your bring a dark coloured swimsuit if possible as it requires machine washing to remove the mud. It is not permitted to wear wet baiting suits in the tour van.

  • The Dark cave requires you to be between 40 and 90kg to ride the long zipline.
  • We do not recommend children under 1.3m to enter the mud cave as it requires balance and agility. Children under 1m are strictly not permitted into the mud cave.

  • All children must occupy their own seats on the dragon boat going into the Phong Nha cave.
  • No GoPros without a wrist strap will be permitted on Dark cave property (as many GoPros have been lost forever during the activities).

We can accept bookings up until 6:00AM the day of your tour, but it is not guaranteed.

Yes. However, the long zipline has weight restrictions. If your child is under 40 kgs they are not allowed to do the zipline. Instead, they go by kayak (while being accompanied by their guardian) to the mouth of the Dark cave. The absolute minimum height requirement for children to enter the mud cave is 1m. However, we do not recommend it for children under 1.3m tall (~6  years old) as small children may find it difficult to maneuver or are uncomfortable in the darkness. If your child is too small to enter the cave, there are plenty of water activities outside of the cave they may partake in.

If you are not between the required 40-90 kg or simply do not wish to participate in the zipline, there will by kayaks available for you to get to the mouth of the Dark cave. One of our guides or representatives will accompany you down the river to meet the rest of the group.

We do not recommend you take a bus after our tour. The schedules are too flexible and the buses tend to depart earlier than our tour ends. We do, however, recommend taking a train for ease and comfort.

Only waterproof cameras with a wrist strap are permitted on Dark cave property. Your cameras are your own responsibility; many GoPros have been lost forever at the bottom of the river/mud bath during the activities. For your convenience, our guide has a GoPro and will be taking photos of your zip lining and inside the mud cave. Check our Facebook postings to see your photos.
