Children can take up the challenge to find the rats hiding on board the ship with the help of a special quiz trail. They can also make their very own plaster rat to take away as a souvenir.
Adult visitors have not been forgotten as they will be give the opportunity to take part in a fantastic free draw for an incredible free flight for their family over London.
"This family-friendly activity, ideal for 5-12 year olds, makes the ship the perfect half term destination," says Brad King, director of HMS Belfast.
"The ship is a great place for a family visit as there really is something for everyone on board. While the children are trying to find the rats, the adults can use the audioguides to really enjoy the atmosphere of the ship. Admission is free for children under 16 so HMS Belfast is also a great value day out for all the family."
