The Serra de Rubió is a mountain range located in Catalonia, Spain, between the comarques of Anoia and Bages, and among the municipalities of Rubió, Castellfollit del Boix, Òdena and Els Prats de Rei.

The landscape of the surroundings is characterized by woods of Aleppo Pine (Pinus halepensis), the predominant species in almost all the mountain range.

However, also the Austrian Pine (Pinus nigra) stands out, mostly in the wet areas in the bottom of the valleys but also in the shady spots, by the side of the Scots Pine (Pinus sylvestris), which is less abundant and lies mostly in some shady spots higher than 700-metre-high (2,297 ft).

Regarding fauna, the main animal species are the roe deer (Capreolus capreolus), the wild boar (Sus scrofa), the red fox (Vulpes vulpes), the European rabbit (Oryctolagus cuniculus) and the European hare (Lepus europaeus).

Besides, a mountain retreat called Refugi Mas del Tronc lies in the northern slope of the Serra de Rubió, where crosses the GR7 path.
