Own-ebne-Ali Forest Park which is located in the north of Tabriz provides a variety of important environmental services for the benefit of present and future generations. These services have economic values that are often hard to quantify in terms of general criteria because they do not produce any revenue directly. However, they provide benefits in terms of the quality of life and recreational opportunities and their economic value can be estimated mainly via some indicators.In this study, Clawson method was used for the estimation of the social and economic values of Ownebne- Ali Park. This method was based on using the maps, preferences and social and economic characteristics of the visitors and the relationship between the cost of access to the park and the number of visitors. Then, the demand curve was drawn based on the data obtained by questionnaires. Calculations suggested the daily recreational-economic value of the park to be 125081000 Rials.The results of the study also indicated that most visitors of Own-ebne-Ali Forest Park were in the age range of 20-30 years. Some 40% of the visitors had a diploma, as their minimum educational degree, and 31.9% of them had a monthly income of 1-2 million Rials.
