Exploring Da River during flood season
Muong Lay, the smallest town in Vietnam, nestles besides the Son La hydropower reservoir on Da river in the northwestern province of Dien Bien. Each year, the water levels on the reservoir rise for around six months. Taking advantage of this seasonal change, Muong Lay has offered boat tours to Tua Chua district in Dien Bien and Nam Nhun district in neighbouring Lai Chau province.
