Come build with LEGOLAND® California at Kidspace and unleash your inner monster.

Something delightfully ghoulish is taking shape at Kidspace! Gather your favorite LEGO® builders and step into a Halloween world where imagination can run wild. Kidspace Museum is teaming up with LEGOLAND® California for two monstrous days of Halloween building, creativity, and imagination.

Get inspired by the miniature LEGO model of LEGOLAND California’s Brick or Treat Street. Then, the real fun begins! Roll up your sleeves and build with your own monsters, goblins, and fantastical creatures—and even dream up the worlds they call home. Included with admission, and free for members.

On Saturday, meet José De Paz, LEGOLAND Master Model Builder. On Sunday, meet Allyson Gail, a professional LEGO builder and former contestant on the LEGO Masters TV Show.

Plus, families who attend will be entered for a chance to win tickets for four to Halloween Season at LEGOLAND® California!  Learn more about all the activities and events happening this Halloween at Kidspace, going on now through October 31.
