Multifunctional Farms, as a practical implementation of Multifunctional Agriculture, offer services and products enhancing Sustainable Development. Current policy lacks a practical tool to assess impact of activities in Multifunctional Farms. In our research we propose and test an assessment tool able to reveal main environmental and non-formal learning indicators in tourism-education-recreation activities, regarding visitors’ opinions. This tool can be used by practitioners, farm managers and other stakeholders, to assess their activities. Also, the tool can help Multifunctional Farms, to find their niche market, profiles of future visitors. This tool covers a huge gap between theory and practice of Multifunctional Agriculture, the tourism-recreation-education activities.
