The Healdsburg Water Carnival, where you can swim all day, eat good food and see who will be first to splash flat on their ass during the floating wine-barrel races! And did we mention that you can float a rubber duckie in an actual competition? The carnival has all of these frills to offer when it sets down at sunny Memorial Beach Saturday for its third-annual fest. Bringing a swimsuit and towel is a must, and activities include a river parade of whimsical floats, Sonoma County’s only floating wine-barrel races, the Great American rubber duck dash with prizes, delicious food prepared by local food truck chefs, children’s games and live music by Big G and Friends. Carnival proceeds go to Regional Parks and the Rotary Club. Have the sunscreen ready on Saturday, July 27, at Veterans Memorial Beach. 13839 Old Redwood Hwy., Healdsburg. Free. 11am. 707.565.2041.
