How much local currency Norway/Denmark

Where in Denmark and Norway? If you stay in the touristy areas, there is a big chance you will not need any cash.

First three nights in Oslo, then Nutshell route to Bergen with an overnight stop in Balestrand. Then Coastal ferry north to Svolvaer, fly back to Oslo, ferry to Copenhagen and similar plan in Denmark. Part in Copenhagen and part in countryside.
Thanks

I spent several weeks in Norway last summer: Oslo - Nutshell/Flam - Bergen - Alesund - Trondheim - Roros - Dombas/Andalsnes - Oslo - Fredrikstad. Many enterprises had "we don't take cash" signs. I encountered only two places where I really had to have cash:

• A luggage locker in the Dombas train station (the toilet at the station took only cards)
• A public toilet in Ekebergparken in Oslo

Use of cash in Norway is so rare that you'll struggle to find a bank-owned ATM in Oslo.

My guess is that $25 worth will be more than you need; have a plan for how you'll spend it at the end, since not every restaurant/shop/hotel will be willing to accept it; supermarkets may work. I don't remember what I did with the remains of my ATM withdrawal (which was probably about $40).

I haven't been to Denmark but included Sweden and Finland in last year's trip. Norway was clearly farther along the path of eliminating use of cash than the other two.

We spent six weeks in Scandinavia in August/September 2022 and only used cash in Denmark. We needed it twice - once at Frederikshavn railway station because the card reader on the ticket machine wasn't working (there was an ATM at the station so we withdrew cash on the spot), and once on a local bus in Silkeborg. We managed both Norway and Sweden using only cards.

Then you'll probably manage without any cash in Norway, but it's probably useful to have a bit of cash for the Danish countryside. Start with maybe 2-300 kr and see how far that takes you?

Use the rest in the airport. Unload all your cash and pay the rest by CC.

We just got back from 2 weeks in Norway, Sweden and Finland and I can verify that not only do you not need much cash, but you'll find very few places that will even take it. I ordered foreign currency from my bank before the trip (because it's fun to look at the money!) but it was completely unnecessary. I actually had a hard time getting rid of it before the trip was over. In the Oslo airport as we departed, we even saw a billboard ad promoting cashless payment with the slogan "Say NO to NOK" :)

I was in both countries last month for 3 weeks. I never obtained nor needed any Norwegian Kroner. Same with Danish currency. I did have the equivalent of about $3 in Danish coins from a previous trip. I used some to buy a transit ticket, but could have used a CC.

I would say don't bother with currency. Especially in Norway where there are billboards about not using cash. (edit: I missed the above reference in the previous post. It was striking!)
