Tiny costumes take over Old Settlers Park at Round Rock's Fall Fun Festival, a celebration planned especially for toddlers and preschoolers. Families can enjoy the Pumpkin Playland theme and a festive outdoor gathering at Lakeview Pavilion without buying an admission ticket. Dress little ones for the occasion, pack for a morning in the park and bring a canned food item if you can to support the Round Rock Food Pantry. The event runs from 9 to 11:30 a.m., leaving the afternoon free for naps.
