Hi, we have a farm at Kim Boi, Hoa Binh near zone of hot spring, ~60km from Hanoi. If you want a holiday with the experience of green life. Contact me. You can stay as volunter. Besides, I can also introduce you to my friends' farms in Northern Vietnam such as Sapa, Thanh Hoa, Bac Kan, Son La... You will experience local culture by living and working with local people. You will have more interesting experiences than just visiting. About me: "Thinking outside the box"
