Located in the historical town of Safranbolu in the Black Sea region of Karabuk, Incikaya Valley is one of the country's oldest established aqueducts dating back to the 18th century, marked by massive stone arches. Today, the canal offers one of the most beautiful panoramic views of the country's skyline, and to provide the best tourist destination the government has built an opaque glass bridge that allows visitors to look through the canal below them.
