Fjords that drop a thousand metres into black water, sun that forgets to set, and towns that treat winter as a reason to go outside.
Midnight sun season
Late May–late July — north of the Arctic Circle the sun never sets; Tromsø and Lofoten run on 3am energy.
Northern lights season
Late Sep–late Mar — Tromsø is the world's most reliable big-city aurora base.
Bergen International Festival
Late May–June — Norway's biggest arts fortnight.
Constitution Day
May 17 — the whole country wears national dress and parades; Oslo's is the grandest.
Emergency numbers
112 police · 113 ambulance · 110 fire. English is near-universal, including with dispatchers.
Mountain & sea
Fjord and mountain weather turns fast — file a route with your hotel, check yr.no and varsom.no (avalanche) in winter. Rescue is free and excellent; the risk is exposure, not crime.
Before you go
EHIC/GHIC helps EU visitors; everyone else insures. Norway is very expensive — a pharmacy ('apotek') consult beats a clinic for small things.
