Oymapinar Dam is located north of Side, in the mountainous part of the Manavgat district, on the Manavgat River. It is a large concrete arch dam spanning a narrow gorge and forming a reservoir that tourists usually know as Green Canyon. The structure is one of the notable engineering landmarks of southern Turkey and is well known for its panoramic views of the water and the canyon slopes.

The dam was built at the end of the 20th century to generate electricity and regulate water resources. Its height is about 185 meters, and its crest length is about 454 meters. A hydroelectric power plant operates at the dam, so the site primarily retains economic importance, while tourist interest is mainly connected with the surrounding landscape and viewpoints.

For visitors, Oymapinar is interesting for its combination of engineering scale and natural surroundings. From here, there are views of the greenish reservoir water, steep limestone slopes, and winding sections of the canyon. Most people come here not for the dam itself, but for walks and viewpoints around the reservoir, from which the structure and the river valley can be seen especially well.

When visiting, it is worth keeping in mind that this is an active infrastructure facility, so access to certain areas may be restricted. On site, it is best to follow the current access rules and signs. For a trip from Side and central Manavgat, the dam is usually considered part of the route to Green Canyon and the upper reaches of the Manavgat River.
