Sierra de Collserola is part of the coastal cordillera, a mountainous, 300 km-long landscape along the Mediterranean Ocean. The park's northern boundary is the Besòs river and Vallès depression, and it is bordered by the Llobregat river and city of Barcelona in the south.
In 1987, a special management and environmental protection plan was established for Collserola. It is based on the principle of protecting and strengthening ecosystems. At the same time, infrastructure construction has allowed the public to use this space rationally, without endangering the park's precious natural and landscape resources.
The site, managed by the Collserola park Consortium, is a diversified spectrum of natural Mediterranean environments, where forest areas predominate. There are also a few agricultural areas.
The park's highest point is on the Tibidabo mountain (512 m). It has a typically Mediterranean climate.
The average temperature is 14°C, with pluviometry of 620 mm/year, although microclimates due to diverse hilly terrain must also be considered.
