Why go
From the seafront, the curve of La Concha and Ondarreta becomes clear, with Santa Clara Island set between the two headlands. The promenade gives a continuous way to read the city from shore, while changing tides visibly alter the width of the sand.
What to look for
- Santa Clara Island sits within the bay between Mount Igueldo and Mount Urgull.
- La Concha and Ondarreta form the bay's two main stretches of beach.
- The La Concha railing follows the curve of the central promenade.
The full story
La Concha takes its name from the shell-like curve of its shore. The bay lies between Mount Igueldo on the west and Mount Urgull on the east, with Santa Clara Island in the water between them. Its present outline developed over a long period as sediment near the Urumea helped connect Urgull to the mainland. The modern promenade sharpened the recognizable curve. Along the shore, a walk can move from Ondarreta through La Concha toward the old port and Mount Urgull. Sections of the waterfront have different names, and the well-known La Concha railing belongs to the central stretch. The bay's shape shelters its beaches compared with the open Zurriola shore, but the tide still changes how much sand is available. This makes the view from the promenade a more dependable way to understand the whole bay than judging it from the beach alone.
Useful to know
- Use the promenade for a bay overview, then choose a beach according to the tide and conditions.
- Allow extra time if continuing around the port toward Mount Urgull.
