Family Activities in Östhammar
Östhammar Municipality is northern Roslagen's gem for families with children. Nature here is magnificent and distances between attractions are short — a perfect base for a varied family holiday.
Forsmarks bruk — Experimentverkstaden
In the well-preserved industrial community of Forsmark you'll find Experimentverkstaden, an interactive exhibition about physics, energy and technology. Children can try experiments, build and explore in a way that makes natural science accessible and fun. The surrounding industrial community with its intact 18th-century environment is an experience in itself for the whole family.
Mineralmuseet
Roslagen is rich in mineral deposits thanks to its bedrock geology. Mineralmuseet in Öregrund/Östhammar lets visitors learn about fossils and minerals — and there's an opportunity to try mineral hunting in practice. A popular activity for curious children.
Gräsöbaden
On the island of Gräsö in the outer archipelago you'll find Gräsöbaden with sandy beaches, rocky skerries, mini golf and boat rentals. A peaceful and family-friendly bathing paradise with the opportunity to explore the island's unique nature. Gräsö is reached by ferry from Öregrund.
Krutudden
Krutudden offers year-round activities — swimming and outdoor life in summer and ice skating when it freezes over in winter. A place for spending time outdoors and getting active in a natural environment.
Österbybruk Herrgård

Tvärnö Animals & Nature
