like they said up there – beer is ca. 10-12 GBP a pint in the bars. Cans of beer in the shops are over 4 GBP each. A burger and chips meal in a cafe will cost over 15 GBP
but buy stuff fresh from the shops and wild camp or stay in cabins and you’ll have a fairly in-expensive time
I do a 30km commute one way 4 days a week. The morning is a quick ferry ride across the fjord and a short 1km ride to the office and then a 30km ride home (mixed off road and bike path)
