Athens vs San Sebastián

Athens

Athens has a hot Mediterranean climate with long, dry summers and mild, wet winters. Summer temperatures regularly exceed 35°C and the Acropolis bakes in the sun. Spring and autumn are ideal for sightseeing. Winter is mild with some rain but temperatures rarely drop below 5°C.

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.

Athens

Athens has a modern metro system (built for the 2004 Olympics), extensive bus and trolleybus network, and a tram line to the coast. A single ticket costs €1.20 and is valid for 90 minutes on all modes. The 5-day tourist ticket (€9) is excellent value.

Walkability: Central Athens is very walkable, though hilly in places. The pedestrianized Dionyssiou Areopagitou walkway around the Acropolis is one of Europe's finest urban walks. Plaka, Monastiraki, and Syntagma are all within easy walking distance of each other. The heat in summer can make walking exhausting — carry water.

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).
