In this study, the effects of visitor acitivities on topsoil hydrophysical properties in two protected areas in northern Bleacksea region were investigated. For this purpose, soil samples taken from study area that was characterized as heavily trafficked site (HTS), moderately trafficked sites (MTS) and control (non-trafficked site). The soil bulk density and soil penetration resistance increased from 1.02 to 1.39 g cm–3 and 0.66 to 1.55 MPa, respectively, saturated hydraulic conductivity decreased from 60.60 to 10.35 mm h–1 in moderately and heavily trafficked sites, respectively, at 0–10 cm soil depth in Ayder protected area. The soil bulk density and soil penetration resistance increased from 0.85 to 1.40 g cm–3 and 0.68 to 1.50 MPa, respectively, saturated hydraulic conductivity decreased from 58.75 to 10.35 mm h–1 in moderately and heavily trafficked sites, respectively, at 0–10 cm soil depth in Kafkasor protected area. The intensity of visitor activities had a negative impact on topsoil hydrophysical properties in the study area in Ayder and Kafkasor. The principles of management in Ayder and Kafkasor protected areas should be revised, and use of this area without a plan should be stopped as soon as possible
