Trick or Treat Trail
It’s a spooky day in Castell Caernarfon, and we’ve hidden a variety of secrets and sweets around our site.
Explore the castle, gather the clues, and enjoy a Halloween treat if you solve our tricks!
Our Trick or Treat Trail runs all day and, while it’s most suitable for primary school-aged children, anyone's welcome to join in.
You do not need to book tickets for this event.
