Our aim for this activity was to show our international students the protected natural park Serra de Collserola, a big mountainous area in the outskirts of the city. Since the weather is quite warm now, we scheduled this trekking session in the evening in order to see the full moon.
The Collserola Park is the largest green space in the metropolitan area of Barcelona. It is not just a park per se, but a big natural space with forests and natural heritage. We met up in the center of the city and headed to the park in a nice walk. The views in the end were so worth it: Barcelona's bright skyline at night and a beautiful full moon.
