Plava Voda (Blue Water) is a large spring, which creates approximately 350 meters long eponymous river, in Travnik, Bosnia, and Herzegovina. It rises under Vlašić mountain, just below Travnik Castle, in the center of Old Town of Travnik. The Plava Voda springs out of a large slit at the bottom of a mountainside, which is situated within the narrow depression in Travnik's Old Town neighborhood, in the heart of the city. Immediately above the wellspring rises an old Travnik's citadel, the Travnik Castle. The wellspring of Plava Voda is a city's main source of potable water. It is also one of the main attractions of Travnik's rich natural and cultural-historic heritage.
