One of the country's largest contemporary art museums. Don't miss the Keith Herring: Art is for Everybody exhibit. Wander the Sculpture Garden and take iconic photos of Spoonbridge and Cherry or the giant blue rooster with the city skyline in the background. Work in a round of Skyline Mini Golf with artist-designed holes. Cardamom at the Walker is a nice spot for lunch. These activities fill up quickly so make reservations.
Head to the Mississippi riverfront where Minneapolis got its start. Stroll the trails and walk a portion of the Stone Arch Bridge where river rushes below and a sense of history swirls up in the cool mist from St. Anthony Falls. A short walk downriver you'll find the Frank Gehry-designed Weisman Art Museum at the University of Minnesota https://wam.umn.edu/
