From the peak of Na Lay Mountain, visitors can view the whole of cloud-covered Bac Son valley.
Houses of the Tay, Nung and Dao ethnic minority people lie scattered in the valley, which is surrounded by limestone mountains.
A river running through immense rice fields makes the scenery more romantic and charming.
Coming to Bac Son Town this time of the year, visitors can swim in streams, visit Quynh Son village and go camping.
