San Sebastián vs Vilnius

San Sebastián

San Sebastián has an oceanic climate — milder and wetter than the Mediterranean coast. Summers are warm but rarely scorching, winters are cool but mild. Rain is frequent year-round, especially in autumn and spring. The Basque coast is greener than southern Spain for a reason.

Vilnius

Vilnius has a humid continental climate with warm summers and cold, snowy winters. Spring and summer (May–August) are the best months to visit, with long daylight hours and pleasant temperatures. Winter is cold and grey but has its own charm with Christmas markets and occasional snow on the baroque rooftops.

San Sebastián

San Sebastián is wonderfully compact and best explored on foot. The entire city from Monte Igueldo to Zurriola beach is walkable within 40 minutes. Local buses cover the wider metropolitan area, and the historic funicular climbs Monte Igueldo.

Walkability: San Sebastián is one of Spain's most walkable cities. The entire center — from the old town to Gros, La Concha to Monte Urgull — is flat and pedestrian-friendly. The elegant waterfront promenade is a joy to walk day or night. Only Monte Igueldo requires a climb (or funicular).

Vilnius

Vilnius Old Town is very walkable — most major sights are within 20 minutes on foot of Cathedral Square. For longer distances, buses and trolleybuses are excellent and cheap. Bolt (rideshare) is reliable and affordable. The city is expanding its cycling infrastructure.

Walkability: Very high in the Old Town. Most UNESCO-listed sights are within 1 km of Cathedral Square. Cobblestones can be challenging; wear sensible shoes.
