If you are interested in organic farming, you can trade a half day of work on an organic farm for farming experience. Generally the farmer will provide your room and board, including meals, in exchange for a half day of work on the organic farm. You do not need any experience because you will be taught what you need to know. This experience can include anything from how to milk a goat to how to pick kiwis.
Make a list of places to help decide where in the world you want to get this experience. You can make this decision by assessing your financial situation. If you want to get the experience in France, you need to check your finances to see if you have enough money to get there and back. Generally you do not need money for accommodations and food. You must also think about your responsibilities. For example, if you have family you must check in on regularly, it is not practical for you to go to a farm outside of your local area. Once you know the general area where you can get the experience, you can move forward with your plans.
