In Trosa Municipality, open plains give way to moraine heights, glacial ridges and rocky outcrops; this varied landscape continues into the archipelago. The municipality has 16 nature reserves; new designations may change the number.
Archipelago Coast and Trails Through Nature
In the Kråmö Nature Reserve, smooth rocks and small beaches invite you to swim. Forests suited to hiking and purpose-built trails offer more ways to explore the area on foot. Access depends on the weather and season. Trosa’s archipelago service runs to the islands of Kråmö and Askö in summer; check the current timetable before travelling. Bokö-Askö is also accessible by boat. There, a two-kilometre trail passes through an old cultural landscape, while the rocky coast offers more places to swim.
The natural areas also differ in the character of their trails. Tomtaklintskogen has marked hiking trails and a diverse range of flora and fauna. Luckebol Nature Reserve, by contrast, has no marked trails: visitors explore independently, following existing paths and making their way through the area. Old pines, mixed coniferous and deciduous forests, small swamp woodlands, leafy forest edges, and stands of oak and hazel alternate with a small meadow. Those interested in plants and early history will find a different focus at Lånestaheden: the limestone bedrock supports rare plant species, and the area is one of the richest archaeological sites in Södermanland.
The Tullgarn och Furholmen area combines deciduous forest, pastures, coastal meadows, wetlands and lakes with a long coastline dotted with small islands and skerries. Furholmen is also known for its calcium-rich rock formations and diverse flora, including rare species. A trail from Tullgarn Palace passes Västerviken, a good place for birdwatching, and runs through oak pastures to viewpoints overlooking Tullgarnsviken. At Nynäs, the coast and activities come together: there are places to swim, boat berths and walking trails. Fishing is subject to special rules; cross-country skiing is also available in winter. Along the Sörmlandsleden, you’ll find short and long hikes, as well as shelters and barbecue areas. Stages 53 to 56 of the trail pass through Trosa Municipality. Check trail conditions before setting out.
Cycling and Other Activities
For mountain biking, two routes of different lengths provide options: the Vitalis recreation area offers year-round activities and an approximately 1.7-kilometre mountain bike trail graded Blue, with green sections. Bergs Gård MTB Arena has approximately 35 kilometres of mountain bike trails. Some activities at Vitalis may be subject to seasonal operating conditions; trail conditions can also change. Hembygdsrundan is an approximately 20-kilometre cycling and orienteering route run by the HittaUt physical activity initiative. It passes through Trosa, Vagnhärad and Västerljung.
The municipality’s activities also cater to other interests: Trosa has two 18-hole golf courses, which operate seasonally. Trosa Aktivitetspark offers a high ropes course with seven routes of varying difficulty, as well as ziplines at heights of 1 to 15 metres. Booking and operating conditions may change; check the latest information before your visit. Trosa havsbad offers a beach, rocks, a bathing jetty and a diving tower; individual facilities may change.
Town History and Cultural Heritage
A self-guided audio tour of central Trosa takes about an hour and features historical images. In the town centre, Garvaregården houses the Trosa City Museum. The property includes a tanner’s house and workshop, offering a glimpse into a former craftsman’s yard. Opening hours may vary by season. On Sävö, a small museum tells the story of the island’s pilotage history; opening arrangements may also vary seasonally. You can also hike the Sörmlandsleden on the island.
The municipality’s churches reflect different historical periods. Trosa stadskyrka was completed in 1710 and consecrated in 1711. Trosa lands kyrka was built in the 13th century, north of the town of Trosa. It has a chapel that is believed to date from the 1420s and contains a surviving image of Saint Anne. In Vagnhärad, the church’s tower and vaults are believed to date from the mid-15th century; the interior also includes a sculpture of the Virgin Mary and a 15th-century altarpiece.
Västerljung Church is also worth visiting for its individual works of art: its oldest part dates from the 12th century. The altarpiece was made in Lübeck towards the end of the 15th century. In winter, Trosabacken offers both downhill and cross-country skiing. Snow and operating conditions vary, so what’s available depends on the season.
