Svolvaer is in Nordland.
A boat from Narvik will take you to Svolvaer in 3½ hours.
Svolvaer is really compact so the best thing you can do is walk.
There's many art galleries here.
It's not so easy to keep to the budget here. Narvesen kiosk is a good place to buy things such as drink. There's a bookshop in the town, art is being sold in many places and overpriced souvenirs are easy to find.
