The morning air off Zurriola Beach tastes of salt and cool Atlantic sweep as you step away from the surf and begin the climb onto Mount Ulia.
The path rises quickly through pines and broom, the city shrinking behind you while the bay widens ahead; gulls wheel and the wind seems to push you toward the narrow strait that guards Pasaia’s harbor. History sits on these slopes: 19th-century watch posts, Victor Hugo’s noted wanderings, and a whaling past visible in the rebuilt vessels at Albaola.
Geology here is coastal karst and sandstone folded by the Cantabrian coast’s tectonic lift; trails alternate rocky scrabble and packed dirt, giving way to flatter coastal promenades as you descend toward the harbor mouth.
Local culture arrives as seafood aromas on the water—fishermen, small shipyards and the Basque habit of long, late lunches. The route ends with a short harbor crossing by boat into Pasaia San Juan, a practical and scenic finale.
Practical guidance: expect roughly four hours of walking with some steep, uneven sections early on; comfortable hiking shoes and layered clothing are advisable. Bring water and a wind layer—the coast can be unexpectedly sharp. The route is suitable for most fitness levels but not for those with serious back, heart, or pregnancy restrictions.
Timing matters—midday light gives the best harbor photos, while late afternoon softens the cliffs. Respect the protected area signage and local fishing operations; staying on marked trails preserves the fragile coastal flora and the trail experience for everyone.

Yes—this tour includes the short harbor crossing; local operators run small passenger boats and the segment is routine but weather-dependent.
Services are limited on the trail; bring water and snacks. There are bars and restaurants in Pasaia at the finish and in San Sebastián at the start/end points.
Children in good walking shape can do the route with supervision; the operator notes it is not recommended for pregnant travelers or people with serious back or heart problems.
Mount Ulia and the Pasaia strait have long been strategic: watch posts and whaling activity shaped local settlements; Victor Hugo and other 19th‑century visitors recorded the area’s maritime energy.
Mount Ulia is a protected area—stick to marked trails to limit erosion and avoid disturbing nesting birds; local guides minimize impact by using established routes.
