Sundbyholm sits on the southern shore of Lake Mälaren north of Eskilstuna, combining the 17th-century castle, a marina, a long natural sandy beach and northern beech forest walks.

The park and trails are open all year. In November and December 2026 Sundbyholm Castle serves its traditional Christmas buffet and hosts the murder-mystery dinner Den Sista Valsen on selected dates.
