Mount Ulia is a minor ridge located east of San Sebastián in the Basque Country, territory of Spain, reaching 243 m at its highest point. The ridge stretching out to the east along the coastline sinks in the strait leading to the Bay of Pasaia. The chain overlooks San Sebastian to the west, with the Zurriola beach and the district of Gros lying right under it. This privileged location turned the place into an important leisure and romantic area in the early 20th century, a condition that has remained up to date, despite the pressure of increasing urban development.
