Cardiff Bay Family Fun Park is returning to Roald Dahl Plass for the school summer holidays, bringing fairground rides, game stalls and free family entertainment to one of the busiest public spaces in the Bay.

The fun park runs daily from 18 July 2026 to 31 August 2026 at Roald Dahl Plass, Cardiff Bay, CF10 5AL, between Mermaid Quay and the Wales Millennium Centre. Entry to the event site is free, with individual attractions operating on a paid basis. Card and cash will be accepted at individual attractions, according to the event information.

The event is aimed at families and children of all ages, with faster fairground attractions alongside children’s rides and a programme of entertainment that does not require a ride ticket.

The location is a practical part of the appeal for families already spending time in Cardiff Bay. Roald Dahl Plass sits in the open public space between Mermaid Quay and the Wales Millennium Centre, so the fun park is positioned close to the main visitor area rather than on a separate out-of-town site.

Rides, stalls and free family entertainment

The confirmed funfair attractions include Dodgems, Fun House, Runaway Train, Bungee Trampolines and Water Walkers. The source information also lists children’s rides, giving younger visitors slower-paced options alongside the larger attractions.

Families can also expect game stalls, with the event listing prizes including large cuddly toys. Food will be available from a selection of sweet and savoury takeaway options on site, which should make it easier to combine a short visit with a longer afternoon or evening in the Bay.

Away from the rides, the programme includes free family entertainment. The listed entertainment includes magic shows, princess sing-a-longs and character meet and greets. Exact show times are not included in the source information, so visitors planning around a specific performance should check for local updates before travelling.

Practical details before visiting

The event is outdoors in Roald Dahl Plass, and the published information says opening times may change because of unforeseen circumstances, including extreme weather. That caveat matters for families travelling specifically for the fun park, especially on days when heavy rain, high winds or other severe conditions are forecast.

Well-behaved dogs are welcome on site, but they must be kept on a lead at all times. Alcohol is not permitted within the event site.

No advance booking requirement is listed in the source details. The key planning points are therefore the date window, the daily opening hours, the free entry arrangement and the pay-at-attraction setup. Before setting off, visitors should check the latest Cardiff Bay event information for any weather-related changes to opening times.
