Everything that is brought into Son Doong must be removed after every tour. This includes even human waste. This is done by the process of composting toilets set up in both camps in the cave. After composting all waste is removed from the cave. These toilets are very hygienic and smell free and good for the environment.
On every tour large gas double burners are used for the majority of cooking to save any wood being used. Only wood that has fallen outside the cave can be collected and brought to camp and is primarily used for cooking rice. No wood at all from inside the jungles in the cave is used. Rubbish bags are in position at the camps in the cave to help with rubbish collection.
A single path is followed when travelling in the cave. No one is allowed from this path without permission from the guides. In certain fragile areas we do not allow anyone to visit. No tourist travels through the cave without a guide.
Nothing is allowed to be taken out of the cave or jungle and no one is allowed to touch any delicate formations.
Washing and bathing is only allowed in certain places where contamination can be limited. In Son Doong at least 5 new species have been identified and these areas are strictly controlled.
After leaving each camp the National Park Rangers do an inspection and sign off a document concerning the state of the camps.
It is everybody’s interest to follow these rules and anyone found disregarding these rules will not be allowed to take part in the tour. These simple rules will allow Son Doong to be kept in good condition for future generations to see this amazing natural wonder. It is up to all the people taking part in the tours to assist us in conservation of this new wonder of the world.
