The national children's museum is handing out the passes as a thank you for people's support over the years.
We have teamed up with Eureka! to give 5,000 of the visits away to Courier readers.
The museum said: “We’ve proud of all we’ve achieved in that time, and know that it wouldn’t have been possible without Calderdale residents’ love and support.”
For details of how to enter the draw, see tomorrow's edition of the Halifax Courier.
Entrants must be Calderdale residents.
