From Monday tourism businesses – and all others – are not allowed to organize karaoke sessions that used to be popular with visitors in the river at the eco-tourism site.
There had also been concerns about inland waterway safety and noise pollution affecting the lives of local residents.
Many tourists have complained about the noise to local authorities.
The tourist site, situated around three kilometers from Hoi An, is famous for its coracle tours that cost VND150,000 (US$6.44) per person.
Visitors can watch crab fishing and fishermen performing a unique dance on their coracles, see the daily life of local farmers, take part in activities like fishing, and eat fresh catch.
