Take the kids to Pinzgauer Saalachtal and spend an afternoon walking along the water's edge. There's something about being near a river that makes you feel calm and peaceful.
When you've finished exploring this Zell am See flowing body of water, why not make your way to Hochkonigs Winterreich, Pilgrimage Church of Maria Alm, and Zell am See Xpress Ski Lift? They're near Pinzgauer Saalachtal and also popular with travelers.
