Can absolutely recommend it.
Tour is done by volunteer english students from danang university.
You are taken to 5 different local spots and a return ferry to an island. (bring your own bicycle)
The real value is in getting to know the students and an insight into local life.
To clear the confusion of the one bad review: the tour is absolutely free. However 50.000 dong is collected up front to pay for the ferry and to pay for donations at the 5 spots you visit (sometimes into peoples homes).
All in all great value. And if you’re up for it the students are happy to have a drink and a bite to eat at a local place afterwards. I had a lot of fun.
Dont hesitate, participate! You help them by conversing in english so they can practice (actual conversation with foreigners is limited to 2 hours a week at their university). They are all fun and energetic, enthousiastic bright young people with good local knowledge. Better than the proffesional scripted tours! Highly recomended.
