Calling all little (and big) monsters! This Halloween, Alexandra Head on Cardiff Bay Barrage will transform into a fang-tastic event for you and your family.
Start your journey by joining the Ghost Ship crew at Mermaid Quay and cruise across the Bay for a frightfully fun arrival at Halloween Island. An abundance of tricks, treats and tasty eats will await you:
- Pumpkin Village
- Sunken Galleon
- Festival of Bones
- Slime It Live!
- Monster Boogie
- Storytelling and shows for the whole family, including The Curse of Halloween Island with Jack and Luna
- Fairground rides
- The Salem Sisters band (twilight only)
- Photo opportunities
- Street food and drink
Day and evening tickets are available which include a pumpkin for every child, a return voyage across the Bay, and access to a range of attractions and entertainment.
Daytime tickets: 10am-5pm
Twilight tickets: 5.30pm-10pm
Tickets can be purchased here
We’d advise using public transport, walking or cycling, if possible, due to the temporary closure of some Cardiff Bay car parks for redevelopment.
Buses run regularly to the Bay, and Cardiff Bay train station is a short walk away from Mermaid Quay. For more information, visit: www.traveline.cymru/.
We hope you have a ghoulishly good time!
