Pack for the actual route
Bring light layers for warm days, something warmer for cool mornings and a separate plan for mountain weather. Comfortable walking shoes matter on steps, cobbles and uneven ground.
Keep essentials close
Carry travel documents, insurance details, essential medication in original packaging, charging equipment and one change of clothes in your cabin luggage. Check airline and destination rules for restricted items.
Dress for your visits
A light scarf and clothing that covers shoulders and knees are useful at religious sites. Easy-to-remove shoes help where footwear must be left outside.
Leave room in the schedule too
Laundry arrangements can reduce how much you pack. Ask about luggage space in the vehicle and allowances on each domestic flight rather than assuming they match your international ticket.
