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

Watching your bag from the water doesn't really work — by the time you swim back to shore, a thief can already be gone with your bag, phone, and cash.

Best not to risk leaving your phone and cash on a beach lounger — Nha Trang's public beach (unlike a private hotel beach) is very crowded, making it nearly impossible to keep an eye on your belongings.

Practical tip: leave valuables (phone, cash, documents) in your hotel safe, and only bring a waterproof phone pouch to the beach that you can keep on you while swimming.

Beach loudspeakers sometimes announce promotions urging people to go to the Long Chau pharmacy for a 'travel map' with a prize worth up to 1 million VND — this sounds like a marketing gimmick or possible scam, so be cautious and avoid giving out personal info or money.
