Parque Florestal de Monsanto
Monsanto Forest Park spans nearly 1,000 hectares of pine and eucalyptus forest on Lisbon's western hills — the largest urban forest park in Portugal and one of the biggest in Europe. For dogs, it's exceptional: wide unpaved forest trails, fresh air, shade even in summer, and relatively few crowds away from the main picnic areas. Dogs must be on-leash in the designated picnic zones but can walk more freely on the forest trails. The park has multiple entry points and can be explored for hours. Several miradores (viewpoints) offer spectacular city views.
Off-leash zone: Leash required in picnic zones. Forest trails are more relaxed — check current CML signage
💡 Enter via Estrada de Monsanto (west side) for the quietest trails. Bring water — fountains are scarce
