Parc des Buttes‑Chaumont

Bois de Boulogne - Massive park (2.5x Central Park) on Paris' western edge. Dogs can be off-leash in most areas except the lakes and formal gardens. Several lakes and woods to explore. Parking at Porte Maillot or Porte d'Auteuil. Metro: Les Sablons (L1) then walk. Some areas can feel isolated - stay aware of your surroundings. Beautiful in autumn. Good for long off-leash runs.
