March in Spain — events that affect travel

Known cultural, religious, or national events that surge prices, fill hotels, or close businesses during this month. Plan around them, or build your itinerary around the ones you'd like to see.

✝️
Semana Santa (Holy Week)

Holy Week processions, especially in Seville and Málaga. Hotels in Andalucía sell out a year ahead, prices 2-3x normal. Some banks and shops close.

Plan: Seville at peak is unforgettable but planning-intensive. Other Spanish cities are quieter and more affordable.
