Over the past years, Son La province has focused on effectively implementing a project to preserve and promote the beautiful traditional cultural values of ethnic minorities in conjunction with tourism development.

To realise its tourism development goal, in recent years, Son La province has implemented many solutions to promote its potential and advantages, and diversify tourism products and types to attract more visitors.

The mountainous district of Bac Yen, blessed with majestic mountains, a cool climate, a “sea” of white clouds,and unique traditional cultures of ethnic communities, is working to gradually turn tourism into a spearhead economic sector and make it develop sustainably. Its tourist attractions include Ta Xua, "Dinosaur's spine", A Phu couple cave, and Xim Vang terraced fields.
