Lisbon has many botanical gardens, most dating back to 18th century from the times of the Portuguese Royal Family.
While most people visiting the city will end up going to either Jardim Botânico de Lisboa (in Principe Real) or Jardim Botanico Tropical (in Belem), there is one more lesser known spot worth visiting and that is Jardim Botânico d'Ajuda (in Ajuda).
This is a little snippet of a morning spent with my younger son exploring the Ajuda Botanical Gardens.
As an introvert and someone who has hard time dealing with busy over-grounded environments,, I actively search for calm and relaxing spots in the city and this is one of those. As it is slightly out of the way from all tourist attractions and certainly not walking distance from the Lisbon central area, it attracts less tourists (or barely any at the time of my visit). There is no cafe here so come prepared with food and drinks.
