Autumn and winter outings in Trosa Municipality

Trosa, Vagnhärad, and Västerljung combine short distances between archipelago bays, town-side forests, and historic wooden quarters. During the autumn break and weekends in November and December, it is easy to pair a morning out in nature with coffee by the Trosaån river or an afternoon film in town.

Activities for children and families

Trosa Activity Park and Lånestaheden. In central Trosa, children and teenagers gather at the activity park for skateboarding, scooters, inline skating, and climbing play. Right nearby, trails climb into Lånestaheden Nature Reserve with forest paths and an Iron Age hillfort.

Disc golf at Häradsvallen in Vagnhärad. Beside the Häradsvallen sports ground in Vagnhärad, the municipality’s 18-hole disc golf course winds through varied woodland and park terrain. The course is free to play year-round and suits both beginners and experienced players.

Trosa Bio at Skärborgarnas hus. At Smäckbrogatan 25 in Trosa, family matinees and evening films are screened at Skärborgarnas hus. Check upcoming screenings in the events calendar.

Libraries in Trosa and Vagnhärad. Trosa Public Library at Östra Långgatan 5 and the library at Navet in Vagnhärad welcome families with children’s reading corners, story sessions, and school-break crafts.

Indoors on a rainy day

When the weather turns wet or windy, several indoor options are close at hand:

  • Safiren in Vagnhärad features an indoor swimming pool for lane swimming, family bathing, and gym training near central Vagnhärad.
  • Public art and galleries along the river – combine an umbrella stroll with a visit to the small galleries along Västra Ågatan and Västra Långgatan; see our guide to public art and galleries in Trosa.
  • Marsipangården and town cafés – warm up with hot chocolate, freshly baked buns, and handmade marzipan in central Trosa.

Outdoors, archipelago and nature reserves

Boardwalk hiking trail through broadleaf forest and wetland in Trosa Municipality.

Autumn and early winter are wonderful times to hike in Trosa when the air is crisp and the trails are quiet.

Kronskogen-Stenbrottet sits right on the western edge of Trosa town. Walk beneath tall pines and spruces to the water-filled historic quarry where sheer rock walls rise from the water.

Borgmästarholmen and Trosa Havsbad at the tip of Öbolandet are easily reached on foot or by bicycle from the town centre. A footbridge crosses to Borgmästarholmen with trails over smooth shoreline rocks and views across the bay.

Nynäs Castle and Nature Reserve on the coast between Trosa and Nyköping offers marked loop trails through oak pastures and along rocky shores, with waterside fire pits for a picnic lunch.

Sörmlandsleden stages 55, 55:1 and 56 connect central Trosa and the harbour with Stensund Castle and the coastline. Read the full overview in our guide to the archipelago and nature in Trosa.

Farm shops, cafés and lunch

Pair your outing with a visit to one of the municipality’s farm shops or lunch restaurants. In our guide to farm shops and second-hand in Trosa you will find local artisan food producers, and the Trosa lunch guide lists weekday lunches in both Trosa and Vagnhärad.
