Traveler reviews

★★★★☆

Lovely warm escape from a UK winter - Yalong Bay's beach and water quality were genuinely good, though it was busy with domestic tourists even outside peak holidays.

Grace L. · January 2024

★★★★☆

Wuzhizhou Island for the day was the highlight - much clearer water than the mainland beaches and good snorkelling. Resort itself was comfortable but fairly generic.

Kevin Z. · March 2024

★★★☆☆

Nice weather and beaches but felt very developed and resort-heavy compared to other tropical destinations. The Nanshan Buddha statue was an impressive half-day trip though.
