Puig d'Olorda, Mountain summit in Serra de Collserola, Spain.
Puig d'Olorda is a mountain in the Serra de Collserola with a summit just under 500 meters elevation that multiple hiking trails can reach from different starting points. A fire watchtower and a large cross stand at the peak, from where views stretch across Barcelona and the surrounding towns.
Limestone quarries operated on the mountain's slopes until 2006, extracting stone that fed cement production in the area. This industrial use shaped the mountain for decades before mining stopped completely.
The hermitage of Santa Creu d'Olorda stands at the mountain's base as a place where pilgrims and hikers pause to rest. It reflects how religious structures have long been woven into the natural landscape of this region.
The summit is reachable via well-marked trails from Sant Feliu de Llobregat, Molins de Rei, or Baixador de Vallvidrera train station. Routes vary in difficulty, so choosing the right path depends on your fitness level and available time.
The rock formations here are limestone, which stands apart from the metamorphic rocks found elsewhere in the Collserola range. This geological difference makes the mountain worth noting for anyone curious about what lies beneath the surface.
