How to keep your phone and valuables safe while swimming at the beach in Nha Trang?

On 1 October 2026 a traveler reported that motorbike riders had stolen a bag near the Seaside hotel; it held documents, including two international passports, and the owners asked for help finding it. The case shows that bags with valuables and documents in this area get stolen not only from the sand while their owners are swimming.

In late July 2026 a participant described a typical scenario: you come to the beach, leave a bag with your phone and some cash for lunch and water, and go for a swim. Even if you watch your things from the water and spot a thief, by the time you get out of the sea, they will have reached the edge of the beach. In their view, keeping an eye on your belongings from the water is not a real safeguard.

In September 2026 travelers advised walking in the evening and going to the sea with company rather than alone, so you don't have to hold your phone in your teeth while swimming: someone from your group can stay with the bags. This matters most for people staying in hotels without their own private beach who use the public beach: in July and August 2026 travelers who had heard about thefts kept asking where to leave their things.
