Most of the working holidays in Taiwan are ecological-oriented; only a few of them focus on volunteering in agriculture sector. Volunteering in farm is a kind of working holiday that builds a mutual-aid relationship between participants and farmers. It enables participants to work in exchange for living experience in the farm and helps the farmer to find labor. Besides, through volunteering in farm, participants, farmers and the nature are reunited together. The research is carried out through four in-depth interview with the participants volunteering in farm. The survey shows motives that prompts participants to volunteer in the farm: to experience different culture and place, to move to a new environment, to explore and gain knowledge, the charm of countryside, the practice of belief and identification, and the diversified types of farm. Participants mainly take part in easy handwork and sometimes also help other non-farm work. To the participants, the personal benefits of farmstay are improving interpersonal and social relations, paying more attention to the rural areas and gaining agricultural knowledge, placing a high value on healthy diet and food education, enriching the quality of life. Participants also make contribution to local farm or even community by serving as workforce supplement, helping the marketing of farm products and enhancing the willingness to immigrate to rural areas. The research has found that volunteering in farm is feasible, and to effectively promote it depends on the accommodation of the farm as well as the participants' clear understanding of it. The study proposes suggestion on participants, farms, related government department and future research. To attract more people devoting in farmstay, it is recommended to build an information platform of volunteering in farm, assisting farmers on developing farmstay package and help them to recruit volunteer through farmers' association.
