They are owned and operated by the British theme park company Merlin Entertainments, which shares a common owner (Kirkbi A/S) with the Lego Group.

Further parks opened in Germany, Japan, South Korea, Malaysia, the United Arab Emirates (Dubai), the United States (California, Florida, and New York), and a Legoland Water Park at Gardaland in Castelnuovo del Garda, Italy in 2021.

Parks in Beijing, Shanghai, Sichuan, and Shenzhen are currently under construction.

Attractions consist primarily of outdoor flat rides, dark rides, interactive play structures, and splash pads, as well as designated stations for playing with Lego bricks.

The resort will see the addition of Peppa Pig Park for 2024, making it the second Legoland resort to have a non-Lego themed attraction and Peppa Pig theme park.
