Cao Bang- Feature destination

Home to a UNESCO-recognized geopark and Southeast Asia's largest waterfall, Cao Bang remains off the beaten track and less busy than neighboring Sa Pa or Ha Giang.

The cool climate of Cao Bang Province that borders China ensures that you can come here all year round. The best time to visit Cao Bang is during the dry season from October to May with little rain.

If you want to see white frost and ice covering mountainous areas in Phia Oac, the second highest peak in Cao Bang, you better come there from November to January as the temperature could drop to below zero degree Celsius.
