More than 6 million tulips bloom during this festival, which features a Dutch market, dancers, trolley tours, big-name performers and three parades, ending with the Muziekparade, with 40 bands and 40 floats.
Watch a kayak whitewater rodeo, take a paddling clinic, make your own paddle or join a group float. There's hiking and rock-climbing, too. In Sandstone's Robinson Park and Banning State Park.
There's a lot going on in this former communal society in eastern Iowa — a 10 a.m. Saturday parade, polka music, keg-tapping, food-sampling, artisan demonstrations and pony rides.
