Alta and Tromsø are only about 175 km apart as the crow flies, and Alta is barely 18 km of latitude further north, which makes no real difference to the aurora. What separates them is geography. Tromsø sits on an island on the Troms coast. Alta lies at the head of the Altafjord in Finnmark, sheltered inland, and that shows up in the weather records, in the length of the evening tours and in how busy the town feels. If you base yourself in Alta, the Small-Group Guided Northern Lights Tour is the evening most visitors start with.

Weather: the inland town is drier
This is the difference most people are really asking about. Alta’s airport station averages about 438 mm of precipitation a year. Tromsø gets about 1,091 mm, roughly two and a half times as much, and it is wetter than Alta in every month of the winter: in December about 110 mm against 37 mm.
Visit Alta says the town “lies sheltered inland at the head of a fjord, so it gets less precipitation than coastal Tromsø”, which it says means “more clear nights on average”. The University of Tromsø’s space-weather observatory makes a similar general point: coastal cloud can be a problem in northern Norway, “so some travelers go inland”.
Treat that as a tendency. Precipitation and cloud are not the same thing, and we found no cloud-cover or sighting statistics for Alta, so nobody can tell you Alta’s odds are better by a particular amount. A cloudy week is possible in either place, and a clear night is possible in either place. Every aurora tour we list in Alta says the lights cannot be guaranteed.
Size, crowds and the tour scene
Tromsø is a city of about 80,000 people, nearly four times the size of Alta, and a place that size has more restaurants and more to do on a cloudy evening. Alta is Finnmark’s largest town, at about 22,000.
Visit Alta describes the town as smaller and quieter, with fewer visitors per tour. That is the tourist board’s own description, and we have no visitor figures to compare it with.
In Alta, we found 16 evening tours with an aurora element on GetYourGuide in November 2026, from big-bus chases to small groups of eight, snowmobiles, ATVs, a reindeer ride, horses and sleighs. Group sizes vary a lot: the small-group tour above takes up to 13 people, and Icecube of Aurora’s Northern Lights Tour up to 8. We did not count Tromsø’s listings, but expect a wider choice in the bigger city. Our tour comparison covers the Alta options one by one.
On price, we haven’t compared the two towns, so we won’t claim either is cheaper. In Alta, the evening aurora tours ran from $129 to $346 per person on the dates we checked in early November 2026; our cost guide has every price.
How the chase works in each
Both towns run the same kind of tour: a guide watches the forecasts and drives to wherever the sky looks clearest. What differs is how far they tend to go.
Tromsø operators describe driving out to the coastal islands, inland, or sometimes towards the Finnish border, and their tours often last 6 to 10 hours. That comes from the operators and from travellers’ forum posts, not from a neutral source, but it matches the geography: from an island on a cloudy coast, the clear sky can be a long way off.
Alta’s evening tours on GetYourGuide are shorter, mostly 3 to 5 hours, and the longest, the Northern Lights Adventure Tour with Fire & Free Photos, runs up to 6 hours. Alta Adventure says it sometimes has to drive quite far and sometimes finds the lights close to town, and it normally has guests back in the centre just after midnight. One reviewer on the fire-and-photos tour describes a drive of about an hour to clear skies while the town was under cloud.
From Alta, the open Finnmark Plateau and the Arctic coast are both within reach, and Visit Alta says experienced hunters head to one or the other. A shorter tour leaves you more energy for a day of dog sledding or snowmobiling.
Getting there and between them
You can reach both by air from Oslo. Visit Alta lists flights to Oslo and Tromsø from Sunday to Friday, with a seasonal direct flight from Frankfurt; check that it is running for your dates. Alta Airport is about 4 to 5 km from the centre, roughly 10 minutes by car or the Snelandia bus.
Between the two towns:
- By air, about 40 minutes. Check current timetables, since the days of operation vary by airline.
- By road, about 6 hours. The shorter route, roughly 298 km, uses two car ferries (Svensby to Breivikeidet and Olderdalen to Lyngseidet) before joining the E6. Without the ferries it is about 390 km and about 6.5 hours.
- By bus, once a day, about 6 hours 45 minutes.
In winter that drive means snow, dark afternoons and the chance of a closed pass or a convoy. Visit Norway’s advice is to keep the headlights on and to watch for reindeer and moose, which are a bigger risk in autumn and winter. Rental cars come with winter tyres as standard.
The Hurtigruten Coastal Express calls at Tromsø but does not call at Alta. Some cruise ships do call at Alta Havn, about 4 km from the centre; our where-to-stay guide covers the port and the hotels near it.
Cold and daylight
Alta is colder. Its winter averages run about 3 to 4 °C below Tromsø’s from November to March. January and February average about -7 °C at Alta Airport, with average lows around -10 °C (14 °F), and Visit Alta says the plateau is colder still, sometimes -25 °C or lower. You stand still for long stretches on an aurora hunt, so this matters more than it would on a city break. Several Alta tours include or lend thermal suits; check the listing before you pack.
The dark season is much the same in both. Alta’s polar night runs from 26 November to about 16 January. By our calculation Tromsø’s runs from about 28 November to 14 January, a couple of days shorter.
Who should pick which
Tromsø suits you if:
- you want a city break with the aurora as one part of it;
- you are travelling on the Hurtigruten Coastal Express;
- you want a bigger city’s choice of tours and restaurants, and don’t mind a long evening on the road.
Alta suits you if:
- you want a small, quiet base where the evening tour is a few hours, not most of the night;
- the drier inland climate appeals, accepting that it improves your odds a little at best;
- you want to combine the aurora with dog sledding, snowmobiles on the plateau, the Sorrisniva Igloo Hotel (open 20 December to 31 March, according to its own site) or the start of the Finnmarksløpet sled dog race on 5 March 2027;
- you are on a cruise that calls at Alta.
If I had four or five nights and no other plans in the north, I would choose Alta for the drier climate and shorter tours. If it was a first trip to Arctic Norway and I wanted a city around me, I would choose Tromsø.
You can also do both. A 40-minute flight links them, so a few nights in each gives you two separate weather systems to work with. Our best time guide covers when to go and how many nights to plan in Alta.
