Sweden has countless castles (or 'slott' in Swedish) from its storied history. Seeing all of them would take ages. I have compiled a list of some of my favorite castles from across Sweden including Uppsala Castle, Kalmar Castle, Kärnan, Borgholms Castle, Gripsholm Castle, Vaxholm Fortress, Örebro Castle, Skokloster Castle, and Carlstens Fästning.

The island of Marstrand sits about an hour north of Gothenburg on the west coast of Sweden. The archipelago of Gothenburg is a sight to see but if you're feeling more ambitious, find your way to Marstrand where you can hike around the whole island, enjoy swedish dishes like skagenröra and kardemummabulle, while taking in views of Carlstens Fästning and Strandverket.

Uppsala is just 40 minutes north of Stockholm by train. It's the fourth largest city in Sweden (with a paltry 200k for population). Make no mistake, this charming city has great importance in Sweden as a whole. While here, you can enjoy Uppsala Castle and Linnaeum nearby. The best place in the city to experience the sunset and Uppsala Cathedral is right along the canal at Gotlandsparken.
