Getting from Bruges to Forshällan (Jokkmokk) is quit a journey.
Train from Bruges to Brussels-Nat.Airport.
Pay attention: getting to the Airport costs you some additional fee 2,16€ called “Diabolo - for improved access to the airport. From Bruges the train brings you to Brussels-North where you find a connection to Brussels-Nat.Airport. http://www.b-rail.be/Flying to Arlanda Airport
If you fly to Stockholm go for a direct flight if it suits you. Otherwise the flight go’s over Copenhagen thereafter to Stockholm on another air plane. If the transit time is too short (less than 2 hours) it could happen that you luggage is still in Copenhagen and you’re already in Stockholm. That was the occasion on my first flight to Sweden. http://www.flysas.comTransfer to Stockholm
If you come to Arlanda Airport you can transfer to Stockholm either by bus – Flybussarna or by train – Arlanda Express. The former is cheaper 99SEK the latter is faster 260SEK for a single trip.

There are several ways getting to the North. But the cheapest is traveling by the overnight train to Narvik – Norway. It’s also the best if you are on a timetable shedule.

Almost there
Murjek the end of your journey by train is a small village. You’ll find only a small building which is the railway station. Further from the railway is an small beautiful roundabout and some old houses and a hotel/restaurant/campsite.
