Castle Rock Ducky Derby

Mark your calendars for Sunday, June 28, 2026, as the Castle Rock Rotary Club proudly celebrates the 30th Annual Ducky Derby & Farmers Market Street Festival at Festival Park in downtown Castle Rock! From 9 a.m. to 3 p.m., experience one of Castle Rock's most beloved traditions—a full day of family fun, community spirit, and small-town charm—with the famous rubber duck race kicking off at 1 p.m. sharp! Watch as 10,000 bright yellow ducks splash into Plum Creek, racing toward cash prizes and glory, while you explore the Downtown Farmers Market, shop local artisans, enjoy live entertainment, and treat yourself to delicious bites from a variety of food trucks. Kids will love the face painting, balloon creations, and games that fill the park with laughter. Every duck you adopt supports Rotary's 501(c)(3) charitable fund, helping us make a difference locally and around the world—so adopt your duck, join the fun, and help us celebrate 30 years of making waves for good!
