IV - To what extent did Vietnam floods affect tourism?
Types of natural disasters in Vietnam, especially floods, have a great impact on the tourism industry. Floods have caused damage to tourism infrastructure, affecting travel and risking the lives of tourists.
Tourism constructions, if facing prolonged floods, will be damaged and degraded. For example, Cau Pagoda in Hoi An, as the rainy season passes, is increasingly seriously damaged. Without timely restoration and protection activities, this tourist spot will collapse in the near future.
During this difficult time, tourism and travel companies will be afraid to organize tours. Because when organizing tours, the companies are meant to protect the lives and health of guests. However, extreme weather disasters are unpredictable and tourists' safety will not be ensured.
For these reasons, during the rainy season, the tourism market is very sluggish, affecting the revenue of companies and individuals who earn their living on tourism.

And do not forget to equip yourself with some knowledge about self-protection, always check the weather of the day before leaving the hotel. Remember, your life is above all, don't endanger yourself for an impulsive moment.
