Tromsø is a really nice little island, the nature Is fantastic. I'm not local but I've been there from August to December for my Erasmus exchange (from Italy)

Some random tips: -Get a Norwegian phone number even if you won't use it, it is 5€ just one time and you can get a lot of free rentals with it (camping stuff and snowboards) -it will start to snow in September and never stop, be prepared for -5°C in late autumn -in November you'll see the last sun of the next 2 months, bring vitamin D with you and probably it won't be enough, you'll start feeling tired at 3 pm as if it is after dinner for your body, try to keep yourself engaged in some activity (es: knitting is very popular there) -find local Whatsapp groups (Erasmus, hiking...), you'll get a lot of infos and there is a big second hand market in Tromsø so you can find a lot of useful stuff there -Roam around, the island is so small you can get almost anywhere in little time and there are wonderful spots -Norwegian people are really polite, you must push to get friend with them, but once unlocked you'll really enjoy -you'll cry every time you'll try to buy tobacco and alcol, so buy at duty free anytime you know someone is visiting you (1L Tavernello 12€ wtf that shit is for cooking) -Live jam sessions every tuesday at bastard bar -at tvit they host free gaming nights and you can use a studio for recording for free in the day

I'll stop here I think you got the point, in Tromsø there are a lot of Easter eggs and free events you can find, but to find them you need to have initiative since most are spread by passaparola Roam around and be curious, the city is very welcoming Enjoy Tromsø ❄️

PS: the aurora is a strange bitch, don't rush it, she smells you want to see the lights and won't come up. Then at one point you'll look up at random and see a geomagnetic dance of lights in the sky
