Parc de Collserola
★★★★★
Massive natural park with family trails just 20 minutes from the center
Best for: Families who want real nature without leaving the city (0-5 years)
💡 Start at the Information Center (Ctra. de l'Església) — they have maps of easy trails and bathrooms. The Font de la Budellera is a short, beautiful route perfect for little ones.
