Autonomous region:




A circular path that takes you inside the park of San Llorenc del Munt and the Sierra of L’Obac, where you can see a sharp landscape of great beauty with a vegetation made up mainly of holm oaks that spreads over a markedly mountainous relief.

Later on, the path reaches the Park of Collserola, the green lung of Barcelona, characterised by its extensive masses of holm oak and white pine and some small oak grove areas, constituting a good representation of Mediterranean ecosystems.
