WWOOF stands for World Wide Opportunities on Organic Farms and refers to the voluntary work on ecological farms all over the world.
For a specific period of time - from one week to some months (or longer) - you live and work on a farm for 4-6 hours per day. Tasks usually involve helping during harvest, renovation tasks, kitchen duties, taking care of the animals and much more. For your support on the farm you get free meals and accommodation. Wwoofing is a great opportunity to get to know foreign cultures and countries with little money.
Information about the programme and contact details of national Wwoof organisations are provided by the international Wwoof-network: www.wwoof.net. The German Wwoof-association can be found under www.wwoof.de. In order to contact farms, you need to register and become a member of the association. The membership costs 20€ for one year.
