Crime in the city is quite under the control of local law enforcement agencies. Security in Vungtau is quite high, and there is little threat to the life and health of tourists. The only thing to be afraid of is theft. Vietnamese offenders are masterful in this business.
The objects of theft are mostly wallets and cell phones of tourists. Most often visitors (and not only) are deprived of property on beaches, in shopping centers and markets.
Therefore, you should follow the main rules of a tourist: do not carry large sums of money, do not show large bills in markets and stores, watch your bags, purses and pockets in crowded places. In case of theft, you should immediately contact the police by phone or the nearest police officer.
