Choose the climbing net or wall as your priority and collect its numbered ticket before exploring elsewhere.
Match activities to age: toddler play for younger children, climbing for older ones, with separate dome-show times.

Free entry does not guarantee popular attractions. Some distribute all daily slots from 8:50; play attractions cannot be booked online.
Climbing has age, size, clothing and safety-instruction requirements; skirts are not allowed.
Children's attractions close at 18:00, earlier than the building's 21:30 closing. Bring cash for paid activities.

My four-year-old loved the big climbing net so much that we went in twice.

There was so much to enjoy; my child was beyond happy and positively excited!

Even an hour early, our chosen planetarium programme was sold out.

At a year and a half, my child could not climb the net independently at all.
