Luleå is a regional centre with a technical university and steelworks in Norrbotten, northern Sweden, with about 70,000 inhabitants. The city is situated at the mouth of the Lule River, in the northwest corner of the Gulf of Bothnia.
Both SAS and Norwegian have several flights per day scheduled from Stockholm Arlanda airport to Lulea airport (fewer during weekends), and with a flight time of about 1 hour 10 minutes it may be preferred over the 14 hour night train.
The airport is situated in Kallax (and thus is commonly called Kallax airport), and lies about 5 km from Luleå city centre, which is accessible via Luleå's public transport (bus number 4), shuttle bus  or taxi. The shuttle bus to the center costs 50 SEK each way, and it's departures are based on the flight schedule.
There are as well scheduled flights to Kiruna/Tromsø (Nordkalottflyg), Pajala (Nordkalottflyg), Umeå/Östersund (Nordic Regional), Gothenburg (City Airline), Sundsvall/Borlänge (Direktflyg), London (one flight every Saturday, SAS), Riga (AirBaltic) and Murmansk/Archangelsk (Archangelsk Airlines).
Luleå is the easternmost point in the Swedish rail network. The city is connected to Stockholm by the over 100 year old Norra Stambanan-rail, which travels way into the inner parts of northern Sweden before meeting the coast again at Gävle. Thus, it can be a good price option between Lulea and the southern parts (from Gävle and south) of the country, but not between Lulea and some of the other larger cities (ie. Umea, Skelleftea, Sundsvall) along the coastline in the northern half of the country. All along the northern coast, bus is the way to travel.
SJ have a few passenger trains scheduled each night between Lulea and Stockholm and Gothenburg. Stockholm is about a 14 hour train, and Gothenburg is over 18 hours; consider paying extra for a bed while booking.
The Malmbanan railway goes to Narvik in Norway via the towns of Boden, Gällivare and Kiruna. Note that the railway ends in Narvik and does not provide a link to the rest of the Norwegian rail network.
The gap in the rail network between Finland and Sweden is covered by buses, which are free with most railpasses. The journey to the Finnish border at Tornio/Haparanda takes 2.5h, and onward to the Finnish railhead at Kemi another half hour.
A fast, cheap and comfortable way of getting to the different parts of the city, is by using the local bus traffic (LLT). Local buses are usually 25 SEK per trip. If you plan on making more than 4 trips, buy a 3-day tourist pass from the tourist office, which allows you unlimited travel on local buses for 100 SEK.
At weekends you should be able to catch a night-bus from most local traffic bus stations about once every hour between 0.00 and 3.00, at a raised cost.
The Luleå archipelago is worth a trip. The archipelago is available through tour boats during the summer. Klubbviken at the island Sandön is a pleasant stop with a nice beach.
Gammelstad is the old church village. It is a part of our national heritage and is originaly the main city. Due to the land rising (the land was pushed down during the last icetime) its harbour got unusable and the new city was established nearer the sea. The church was made in 1492. Same year as Columbus discovered America.
Luleå tekniska universitet (Luleå University of Technology, LTU)  was established in 1971. Its faculties now include Engineering, Computer Science, Music, Wood Technology, Business, Mining and Space Science. It can be reached with buses 4, 5 and 8 in the direction of Porsön.
Shopping, Europe´s first and largest (in 1955) indoor shopping mall is in the town centre.
The Bishops Arms - A pleasant Swedish take on a British Pub. Food is always pretty good, bartenders are friendly, and solid beer selection. The pub is attached to the Elite Hotel. Only thing to keep in mind is you need to order everything from the bar, including food.
The Corner Bar - Solid sports bar with good food. One of the better pizzas you'll find in the city center. Can get crowded during a Hockey game if the local team is on.
Club Cleo  and STUK  are popular late-night dance clubs, with the former being located in the city center (next to the Quality Hotel) and the latter on the campus of LTU. You need a student ID or a special "guest ticket" (which can be purchased by LTU students) to get into STUK. Quality Hotel guests get free entrance to Cleo until midnight.
Elite Stadshotellet - Clean and one of the nicer places in town. Right next to the Main Street and attached to The Bishops Arms pub.
