Let’s do a hike from the neighbourhood Jardim Botânico to the viewpoint Vista Chinesa and back. The whole trip is about 7 km and 400 m in elevation gain. If we feel like it, we could take a slightly different path down. Meeting point: in front of the Zona Sul supermarket next to the botanical garden, Rua Pacheco Leão 16. From there it is a 20 minute walk to the start of the actual trail.
