Mount Ulia, Mountain summit in San Sebastián, Spain.
Mount Ulia is a coastal summit east of San Sebastián that rises to about 243 meters and offers paths with views over the Cantabrian Sea and Zurriola Beach. The hiking routes are clearly marked and extend across the mountain terrain toward Pasajes.
In the 16th century, observers stationed at the peak used bonfires to signal the arrival of migrating whales to hunters in Donostia below. This early warning system was essential for the local whaling industry that sustained many families in the region.
This summit has served as a recreation area for hikers since the early 1900s, drawing people seeking outdoor activities and coastal views. The marked routes here connect with the Camino de Santiago pilgrimage path, bringing travelers through the landscape.
The hiking path is clearly marked with white and green signs starting from the Gros district, making navigation straightforward for most visitors. Wear comfortable hiking shoes and allow several hours depending on your pace and which sections of the trail you choose to explore.
The 1898 coastal defense installation left behind underground corridors and artillery positions aimed at the sea, now largely hidden within the landscape. These military remnants reveal how the region once prepared for external threats.
