Sweden
Norrtälje is the main town of the Roslagen coastal district, 70 kilometres north of Stockholm along the Stockholm Archipelago's northern shore. Sauna culture here benefits from immediate archipelago access — ferry services connect to dozens of outer islands where hired sauna cabins sit on bare rock above the Baltic. The Norrtälje Kallbadhus runs a historic sea-bathing and sauna pier tradition. Swedish bastu etiquette throughout: swimwear in mixed sessions, quieter than Norwegian floating sauna culture. Norrtälje is popular with Stockholm residents as a weekend archipelago sauna destination.
Norrtälje Badhus & Spa is the main facility. The Roslagen archipelago has cottage saunas accessible by kayak or small boat throughout the summer season.
Gateway to Roslagen — one of Sweden's richest archipelago landscapes. The combination of an 18th-century wooden town and Baltic island saunas makes it one of the most authentic Swedish sauna destination contexts.
Inner bays warm to 20–22°C in July. Outer archipelago is colder. Winter temperatures reach 2–5°C with ice in cold winters.
