In late July, Doan Manh of Hanoi and some of his friends got into an open pickup truck and spent a weekend on the banks of Hoa Binh Lake.
From Hanoi, via Thang Long Avenue, it takes one and a half hours to reach a picked spot on the lake.
Hoa Binh is one of the country's biggest man-made freshwater lakes, born together with Hoa Binh Hydropower Plant in Hoa Binh Province.
