Recreational use represents one of the major functions of the forest areas in Turkey. Owing to the fast and inappropriate urbanization trend and increasing population, Forest Service is going to face with a substantial increase in the recreational demand in the near future. In this paper impacts of recreational activities on some hydrological properties of a deciduous forest ecosystem have been evaluated. Soil samples were taken in addition to a 2 years water quality monitoring study. The water quality study on the creeks did not reveal a statistically significant deterioration in the stream water but the effects of trampling on some soil properties were evident. The bulk density values increased with the intensity of recreation and the percentage of sand fraction was also higher at the intensive recreation areas (75.15 > 72.19). The soils of the stream banks in the recreation area had fairly good saturated hydraulic conductivity (SHC) values, however affected from the intensity of recreation. In general, the recreational activities in the area found to be not conflicting with the water production function of the watersheds.
