Santa Ageda mendatea — 8.4 km at 6.6%, category 1, 551 m of ascent. Category comes from our own scoring (average gradient squared × length), so it is comparable across every climb on the site.

Cycling in San Sebastián means relentless short, steep climbing rather than long alpine tempo. The Basque hills rise straight out of the sea, so the road starts tilting within minutes of leaving town. Surfaces are generally good, the green is humid and dense, and a single ride swaps coastal balconies over the Bay of Biscay for tight inland valleys. Very little of it is flat, and even the linking roads between climbs keep nudging up and down. A mid-ride café stop is completely normal here and worth building into the route.

Jaizkibel Mendatea is the most approachable of the local marquee climbs: 8.5 km at 5.1% average with a maximum around 11.1%, gaining 434 m to a summit at 455 m. It is a rhythm climb rather than a wall, so a fit recreational rider can hold a steady cadence the whole way, and the start in Pasaia sits only about 11 km from the city. The catch is exposure. The ridge road runs high above the sea, and wind off the Bay of Biscay can make an easy gradient feel much harder.

Plan on three to four riding days in San Sebastián to cover the essentials properly. That gives you Jaizkibel Mendatea, Erlaitz and Aldura as separate days, with recovery spinning along the coast in between, all from the city and with no transfers. Stretch it to a week and you can add Santa Ageda mendatea near Azpeitia, 27 km away and topping out at 700 m, plus Arrate above Eibar some 40 km out — both effectively full-day outings.

Yes — bike hire exists in San Sebastián, so arriving with just shoes, pedals and a helmet works perfectly well. Reserve ahead in the busier warm months, and ask for gearing suited to gradients like the 10% average on Aldura rather than assuming a standard setup will do. San Sebastián Airport sits about 16 km from town, which makes travelling light genuinely practical.
