A NOTE ON
The waterfall and streams found on Phu Quoc Island are popular picnicking & make-shift jungle karaoke locations for the inhabitants of Phu Quoc, who come here during their days off to enjoy some down time with their friends and loved ones. They eat, sing, and enjoy life in the presence of mother nature. After they have finished enjoying the peaceful jungle scenery, they normally do not take their garbage back with them - which can be seen scattered throughout the area.
This scene normally shocks visitors to the island who can't believe people would just leave behind trash in such a beautiful setting. Until the Vietnamese government educates the local people about the importance of environmental conservation, these beautiful environmental areas will be spoiled by trash.
This is not to say that these natural attractions should be avoided, but for visitors to be less judgmental while visiting them and maybe pickup some trash while you are there.
