• Peacocks on the loose along the paths and balustrades, so younger kids can watch them up close
• Two entrance gates, on Calçada da Ajuda and Calçada do Galvão, so you can come in from either side
• Autumn fair in October, the yearly Festa do Outono with plant stalls, kids' activities and theater, included in the garden ticket

Portugal's first botanical garden, laid out in 1768 beside the Ajuda Palace to teach the royal princes. It sits on two levels. The lower terrace is a baroque parterre of box hedges around a large fountain carved with serpents and sea creatures, with herb beds and nurseries. The upper level has ponds and a tree garden of tropical plants. Peacocks roam the paths, and the terraces look out over the Tagus.
