kid-friendly 53 Get The Wiggles Out DUPLO Playtown at LEGOLAND California, Carlsbad Little kids can sometimes get sidelined by ride height requirements at theme parks, but preschoolers rule at this hilltop play area within the San Diego County park. Tots will love exploring 10 different playhouses- such as a barn, grocery store, and hospital-that are outfitted with slides, mazes, and lots of bigger DUPLO plastic bricks for building. It's also home to the LEGOLAND Express, a mini train geared to ages 5 and under. 36 | VISITCALIFORNIA.COM THIS SPREAD, FROM LEFT: LEGOLAND® CALIFORNIA RESORT; COURTESY SAN DIEGO ZOOhttp://www.VISITCALIFORNIA.COM
