In the outskirts of Barcelona, Spain, there are lots of things to see and do, particularly when it comes to enjoying nature. Here there are plenty of green spaces and natural spaces to go trekking and hiking in.
In this city in Catalonia, Spain, you can practice hiking in the Commarch of Osona, and in Villabrau where you can hike all the way to Sant Segimon. In Les Baumes (the same commarch) you can hike up to Montserrat, or trek to the Les Planes Railway Station. Girona and Tarragona also have nice places to go hiking.
