Rome's botanical garden sits on the slopes below the Janiculum in Trastevere, on land that once belonged to Palazzo Corsini. It has thousands of plant species, including palms, bamboo, Mediterranean plants, medicinal herbs and a scent-and-touch garden designed for visitors with visual impairments.
It is a good place to slow down when Trastevere feels crowded. Combine it with the Janiculum views above or the lanes around Santa Maria in Trastevere below.
