Plava Voda (Blue Water) is a powerful spring emerging from the base of Mt Vlašić at the western edge of Travnik's old town, creating a short, fast-flowing river that runs through a tree-shaded valley with traditional wooden buildings along its banks. The water is ice-cold, crystal clear, and brilliant blue-green where it deepens — the name is entirely accurate.
The area around the spring is the most pleasant in Travnik: there are several cafes and restaurants with terrace seating above the stream, and the sound of rushing water and the cool air under the trees make it an excellent place to stop on a warm day. The short walk from the bazaar takes 10 minutes. The Elči Ibrahim-pašina Medresa, one of Bosnia's oldest Islamic schools, stands nearby.
