The Quinta Vergara is the green heart of Viña: a large nineteenth-century landscape park climbing into the hills behind downtown, full of mature trees, fountains, and quiet lawns. It is the easiest place in the city to escape the traffic, and a long lunchtime walk under its araucarias is one of the best things to do here.
Inside the park stand the Palacio Vergara, an ornate 1908 mansion now used as a fine arts museum, and the Quinta Vergara Amphitheatre, the open-air arena that hosts the famous February song festival. Both are worth visiting; the gardens are free.
