Karlskrona (population apprx. 35,000; greater Karlskrona apprx. 60,000) was originally established as a naval base in 1680, during the reign of King Carl XI, after whom the town is named (Karlskrona: King's Crown). The town continues to host a naval base  and is the largest city in the county of Blekinge.
The town centre lies 5 km south from the mainland on the island Trossö. The old shipyard, the naval base's oldest constructions and the three churches located on Trossö are listed on the UNESCO World Heritage list.

Karlskrona Maritime Museum, Stumholmen, . A very large maritime museum on the waterfront with spectacular vistas. Most of the exhibits are in Swedish, so be sure to pick up an audio guide. The exhibits consist principally of a very large and impressive collection of wooden ship models as well as life size interiors of ships that can be walked through. In addition to the museum itself, the complex houses a very popular smorgasbord that you'll find packed with Swedes from around 11.30 am onwards, and a gift shop. Outside the museum you'll also find some disused ships/submarines that are worth a look, and Karlskrona's famous light house. Price: 95SEK for adults in the summer; free in the winter.
Brygga/Dragso, Dragso. Arguably no visit to Sweden would be complete without getting up close and personal with some cute little red wood houses and Dragso does not disappoint when it comes to providing one of the best examples. The island has a gorgeous little cluster of red wood summer homes located at Brygga. In addition to this, Dragso has some lovely beaches; great for swimming in the summer and for quiet, isolated walks in the winter. Dragso also hosts a large camp site, which includes all the usual amenities AND a fun little mini golf course. Dragso is a fair way out of Trosso, so consider taking a bus, putting on some good walking shoes or hiring a bike.
Boda Borg, . Fun and adventure in unique Quests. This place is great for team building exercises or just for quirky, ultra-competitive groups.
Hire a Bike. While not completely flat, Karlskona is replete with the usual Scandinavian complement of bike paths and riding makes a good, healthy way to get around town and really take in the expansive natural beauty of the islands. Try Sportkompaniet at 9 Hantverkareg (near the junction with Konstapelsgatan): 100SEK for 1 day; 170SEK for 2 days; sliding scale for longer hires.
Pedestrian Mall (Ronnebygatan and Radhusg). While certainly no Stockholm or Copenhagen when it comes to shopping, little Karlskrona still punches above its weight when it comes to shopping. It has all the Scandinavian high street favourites, including an impressively large H&M, a Dressman and an Ahlens, to name just a few of the shops. In one of the malls off Radhusg you'll also find an ICA (pronounced Ik-ka) supermarket, a range of smaller shops and the Systembolaget (the state owned, monopoly off licence/bottle shop/liquor store), one of only two places in Karlskrona where you can buy beer and wine with alcohol content exceeding 3.5% and spirits for home consumption.
Pedestrian Mall (Ronnebygatan and Radhusg). There are a range of places to eat centred around the main pedestrian mall and the square on the top of the hill in Trosso. Perhaps it's best to take the same approach as the Swedes and cruise the mall until you find something you like the look of. Watch out for smorgasbord offerings, like at the restaurant above Ahlens (75SEK for the smorgasbord, including an assortment of dishes, a light beer or sparkling water, bread, salad, tea and coffee). Other options include the multiplicity of kebab shops (with seating), the ubiquitous Wayne's Coffee, a great Sushi place near Wayne's coffee, PM (a pub located in the same mall as McDonald's), caffe 1334 (located opposite ICA) and the bustling smorgasbord inside the Maritime Museum.
Pedestrian Mall (Ronnebygatan and Radhusg) / Town Square. Start in the pedestrian mall and crawl your way along and up towards the main town square. Places come in and out of vogue regularly, but some that have consistent popularity include the Fox and Anchor (an English style pub; regrettably no relation of its cracking Gastropub namesake by Smithfield Market in London), and the rather lame PM.
Pedestrian Mall (Ronnebygatan and Radhusg) / Town Square. There are a range of places in the city centre, most of a reasonable standard, although in typical Scandinavian style, they don't come cheap. Consider using an online booking engine to find the cheapest prices.
Camping / Summer Cottages. In the summer months, consider camping on Dragso or renting a summer cottage. Contact the tourist office for more information (+46 (0)455 30 34 90).
