Spoken languages: Norwegian is the official language, but nearly everyone speaks fluent English.
Local habits and customs: Few Norwegians tip at cafés, but rounding your bill up by a few kroner is pretty standard and considered polite. Drinking alcohol in public places is not permitted, and being drunk on the streets can get you arrested.
Currency: The currency is the Norwegian Krone (NOK). Credit and debit cards are widely accepted, but having a little cash for smaller purchases is advisable.
Getting around: Oslo’s safe and efficient public transport system, Ruter, consists of buses, trams, a small underground rail system and local ferries. In Zone 1, flat-fare tickets cost NOK 39 (£3.50) if purchased before the journey, NOK 59 if purchased from a bus or tram driver or on a ferry. A single ticket costs NOK 40 (£3.50), while a 24-hour pass is NOK 117 (£10). Tickets are easily purchased through the Ruter app or at kiosks.
Electricity and plug types: Norway uses the European standard 220 volts with Type C and F plugs. UK travellers will need a two-pin adaptor.
Time zone: Oslo is in the Central European Time (CET) zone, 1 hour ahead of GMT. It observes Daylight Saving Time from late March to late October.
