Visit this reserve is good if you are traveling from the town of Son La to Nghia Lo in the province of Yen Bai. The whole route is very interesting, it runs between the mountains and other natural reserve – Phu Luong. Ta Sua nature reserve still holds the hallmark of the place untouched by commercial tourism, and that is good.
