Tours and tickets in Oslo

Each site opens on its own search: choose your dates there. A few open on their home page, where you type the place too. Links marked Ad pay us a commission if you book, at no extra cost to you; most pay nothing, and what a site pays never decides whether it is listed or where. How we rank

Sights and their lines from Wikivoyage (Oslo/Inner East, Oslo/North, Oslo/Sentrum, Oslo/West), licensed CC BY-SA 4.0; in order of how often each one's Wikipedia article was read on phones in the last 12 months.

Rain days are the days with at least 1 mm of rain, as a weather station counts them.

Weather read at Karl Johans gate, the centre, 37 km from the airport (OSL): ten years of ERA5 and ERA5-Land reanalysis, through Open-Meteo's open data.

A busy month is a crowded one, not a bad one — usually it is crowded because the weather is good. It is flagged rather than scored down, and crowds alone never make a month “avoid”: that is reserved for weather worth skipping.

How busy it gets

Busiest from June to August; quietest in February, March, April, November and December.

Then and now

Oslo's April days now average 10.6°C, 2.7°C warmer than in 1981–1990. 2 of 12 months are clearly warmer.

Getting there

How far Oslo is, and what it costs, depends on where you set off from — the months above do not.

Being there

On arrival

  • Paying — Visa and Mastercard are taken almost everywhere, usually by tapping, and you can go days without cash; Vipps, the local payment app, needs a Norwegian bank account. Staffed shops must still accept cash for sums up to 20,000 kroner.
  • UPI, for visitors from India — Not accepted for paying here; bring a card that works abroad.
  • Tipping — Not expected: in restaurants round up, and 10% is generous. Taxi drivers do not expect a tip.

Getting around Oslo

Buy tickets in the Ruter app, or on a travel card (50 kroner) from Narvesen, 7-Eleven or Mix: a zone 1 single costs 46 kroner and lasts 60 minutes, changes included, and a 24-hour ticket 137 kroner. Buses and boats sell dearer singles on board, for cash only; trams and the metro sell none. Ruter tickets for the airport's zones work on Vy's trains to the airport, but Flytoget, the airport express, needs its own ticket.

  • Apps — Rides: Bolt, Norgestaxi, Uber. Maps: Google Maps, Apple Maps. Messages: Messenger.

Oslo has a comprehensive public transport network, consisting of trains, metro, trams, buses and ferries. The network covers the Oslo municipality and the Akershus county surrounding the city. More on Wikivoyage

Help

    TravelCharika is not an emergency service: we cannot call for help or send anyone. Numbers can change; if one fails, ask someone local or your hotel.

What Oslo is like

Worth seeing

Getting in
Oslo is served by two airports: Oslo Airport, Gardermoen, Sandefjord Airport Torp. Oslo Airport is the largest of the two and is the main international gateway to Norway. More on Wikivoyage
Staying safe
Police (Emergency only). If you are unsure which emergency number to call, 112 is the central for all such rescue services and will put you in contact with the correct department. More on Wikivoyage
Staying healthy

Kind of place

Oslo is in Norway, Europe. Distances are great-circle, so a short one can still be a long way round.
