Discover Collserola, a mountainous protected natural area within walking distance of the city. This route offers spectacular panoramas, a visit to the picturesque arboretum, a glimpse at the beautiful modernist suburban architecture and a chance to find your way through the pine forests to hidden natural springs.

The route starts from the marvellous medieval streets of Mura town and then ascends the picturesque slopes of Serra de l'Obac up to its highest point Castellsapera 939m. Most of the route passes through wooded spurs overgrown with deciduous trees, but pine trees appear more often towards the end. Impressive panoramas of the surrounding spurs, cliffs and rocks of bizarre shapes open up all the way. We also will meet several grots and traditional mountainous shelters, remaining of medieval tower and an old natural spring
