Os Waterfall is a natural waterfall located within the boundaries of the Araklı district of Trabzon province in Türkiye. Situated in the Turnalı Neighborhood, the waterfall is visited by local residents and tourists due to its natural beauty, ecological diversity, and tourist potential. Maintaining its natural structure and exhibiting year-round water flow, this waterfall is among the notable natural attractions of the Eastern Black Sea region.
Os Waterfall is located approximately 25 kilometers from the Araklı district center, within the boundaries of Turnalı Neighborhood. The waterfall has an elevation of approximately 254 meters. This natural formation, situated on a west-facing slope, is notable for its height of 20.3 meters and width of 4 meters. The area covering approximately 60 hectares exhibits a lower slope topography.
Feeding year-round on snowmelt and rainfall, Os Waterfall maintains a continuous flow that reflects the typical humid climate of the Black Sea region, contributing to a balanced hydrological system. This characteristic has made the waterfall both an important water source for natural ecosystems and a visually striking element of the landscape.
The land on which the waterfall is located is state property. The site is under the supervision of the Araklı Forest Management Unit, which operates under the Sürmene Forest Management Directorate, affiliated with the Ministry of Agriculture and Forestry. The area is managed under state control to maintain a balance between conservation and use.
The Araklı Municipality has undertaken various development and promotional activities around Os Waterfall. Directional signage has been installed, and a stone mill located near the waterfall, which had ceased functioning, has been restored and integrated into tourism infrastructure. Thanks to these efforts, Os Waterfall has become a destination visited by both domestic and international tourists.

View from Os Waterfall (Black Sea Culture Inventory)
Evaluations conducted under the Eastern Black Sea Cultural Inventory Project have identified several deficiencies in the area surrounding the waterfall. One of the most prominent issues is the insufficient number of informational signs introducing the site. Additionally, limited promotional activities hinder the full realization of the waterfall’s potential. Therefore, it is recommended to increase the availability of informative materials and strengthen promotional strategies for the site.
