Legoland Windsor
LEGOLAND Windsor is a family theme park built on the former site of the Windsor Safari Park, 30 minutes west of London. The park is aimed squarely at families with children aged 2-12, with highlights including the Haunted House Monster Party drop tower, the Dragon coaster through LEGOLAND Castle, the MINILAND models, and a full LEGO-themed water playground.
School holidays and weekends get extremely busy - Windsor is a long-standing family day-trip destination for London. Check live wait times before heading to the busiest attractions, and use the crowd calendar to pick a quieter midweek day if possible. The park is quite compact, so queues on popular rides can stretch quickly once the gates open.
