London vs San Sebastián

London

London's reputation for rain is somewhat exaggerated — it actually receives less annual rainfall than Sydney, Rome, or New York. However, drizzle is frequent and skies are often overcast. Pack layers and a waterproof jacket regardless of season.

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.

London

London's transport network (TfL) is extensive and efficient. Use a contactless bank card or Oyster card for the best fares — a daily cap of £8.10 (Zone 1-2) means you'll never overpay. Paper tickets cost significantly more. The Tube is the backbone, but buses and walking are often better for seeing the city.

Walkability: Central London is very walkable and walking is often faster than the Tube for short distances. The South Bank riverside walk from Westminster to Tower Bridge is one of Europe's best urban walks. Green parks (Hyde Park, St. James's Park, Regent's Park) connect neighborhoods beautifully on foot.

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).
