Trumön Lake has a nude bathing beach located on a peninsula in the northern end of the lake Multen about 6 km north of Mullhyttan.

The beach is owned and run by the naturist association NF Bergslagens Solsport, and the nude bathing area is open to public provided they behave in a naturistic way.

Large open spaces on the lawn between high birches. The shallow sand beach transforms to a little more muddy consistency further out. This is a great place for kids.
