How we verified this.
Is Oslo worth visiting during Norwegian Constitution Day?
Packed on the event day; the nearest calm days are Lively. our forecast
Worth it if Norwegian Constitution Day is why you're coming — expect Packed days; if crowds are your concern, it is the one time to avoid — the calm week of 20–22 May 2027 is the quieter plan. advice
Where are the crowds in Oslo during Norwegian Constitution Day?
This is the day Oslo does crowds. The parade route to the Palace and the streets around it are packed with families, and everyone is dressed for it; it is a city celebration rather than a visitor event, and the pavements are full.
Parade days and street closures
The parade route runs to the Palace, and the city publishes the route and the timetable each year. The centre is on foot for the day.
Times and routes change: www.visitoslo.com is the organiser's own page and the authority.
Our crowd forecast is an informed estimate, not a guarantee — check with the organiser and/or local authorities before you plan around it.
our forecast marks a number we worked out from published data; advice marks something we think. Never the other way round.
