Sometimes called "Willing Workers On Organic Farms", WWOOF is a network of national organisations that facilitate placement of volunteers on organic farms. WWOOFing aims to provide volunteers with first-hand experience in organic and ecologically sound growing methods, to help the organic movement, and to let volunteers experience life in a rural setting or a different country. WWOOF volunteers ('WWOOFers') generally do not receive financial payment. The host provides food, accommodation, and opportunities to learn, in exchange for assistance with farming or gardening activities. A fantastic way to spend your time abroad and meet great people while traveling on a budget. Highly recommended!
Below is the trailer to the upcoming documentary about the organization.
