Viroit Park sits just outside Gjirokaster around a small lake fed by cold springs. It is not as important as the castle, bazaar, or Ottoman houses, but it gives the stone city a useful soft edge: water, trees, restaurants, and a place where local families come to cool down.
Treat it as a pause rather than a headline sight. After climbing the steep lanes of Gjirokaster, the flat lakeside path and mountain reflections feel quietly restorative. It is especially pleasant in warm weather or if you have your own transport.
