Cardiff Castle 

Who doesn’t love visiting a castle? Cardiff has an epic castle within the city and it is one of the best landmarks and historical sites in Wales.

Cardiff Castle often has events taking place so it is always a good idea to check the website to see if there are any events planned. 

National Museum Cardiff

A museum is always a great place to take the kids during the summer holidays. It can be a very budget-friendly day out as it is free to enter, although be aware that some exhibits that are only there for a short while may have a charge applied. The exhibits are full of history, science and technology information, as well as having things that the kids can get involved in. The museum has plenty going on during the summer holidays that get the kids involved and learning too. A great way to spend some time if the weather isn’t too great.

This is an open-air museum which chronicles the historical lifestyle, culture and architecture of the Welsh people. Like with the National Museum St Fagans National Museum of History will have a whole host of things for the children to do during their visit.
