Technically, the attraction is for all ages. We saw a 3-year-old laughing and a 5-year-old crying, so it really depends on the child’s tolerance.
Most kids enjoyed it, but the underground tunnels and pathways can be very scary, especially for younger ones. You can skip these areas, but we feel this would miss out on a lot of the attraction.
Plus, the narrow pathways and stairs make most of the attraction impossible for pushchairs.
If you are with a child that needs a pushchair, scares easily, doesn’t like the dark, or loud noises, you may want to wait until they are a little older.
