Legoland California
LEGOLAND California sits in Carlsbad, 30 minutes north of San Diego, and was the second LEGOLAND park to open (1999). It includes the main theme park, a SEA LIFE aquarium and a separate water park, all aimed at families with children up to about 12. Highlights include The Dragon castle coaster, Driving School, Coastersaurus, and a MINILAND USA built from around 32 million LEGO bricks.
California's year-round mild weather keeps crowds steady, but Southern California school breaks and summer weekends drive queue times up significantly. Check live wait times before tackling The Dragon and the flying school, and use the crowd calendar to pick a midweek visit if you want a relaxed pace.
