Serralada de Marina Park, Nature reserve in Alella, Spain

Serralada de Marina Park is a protected natural area located between the Besos River and Can Bordoi Pass, featuring rolling hills and rocky slopes. Multiple hiking paths wind through the terrain, guiding visitors across different elevations and through varied vegetation zones.

The area received official protection status in 2002 following an agreement between local municipalities and the Barcelona Provincial Council. This designation ensured the long-term conservation of the natural space.

The park serves as a gathering place where visitors and locals connect with the Mediterranean landscape and its natural character. People use the trails to experience the regional terrain and understand how nature shapes life in this part of Catalonia.

The park is well-served by marked trails that suit different fitness levels and hiking abilities. Spring and early autumn offer the most comfortable conditions for walking and exploring the slopes.

In the central and highest part of the range, between Puig Castellar and Turó de Galzeran, weathering of the granite has produced the so-called "camps de boles" — fields of rounded boulders. This same central stretch holds most of the park's viewpoints over the northern half of the Barcelona metropolitan area.
