  • Booking not needed

It's the Year of Reading, and what better way to get involved than with Undercover Readers - A top secret trail. A fun adventure around the park in search of clues with riddles to solve.

Can you crack the riddles and complete the mission? Follow the trail and collect your stamp — plus a special prize (while stocks last).

Along the way, step into the Story Den, a cosy hideout filled with books to enjoy and inspire. With our collection of story stones, children can create their own characters, adventures and imaginative tales, shaping stories as bold or as imaginative as they choose.   A relaxed and engaging activity for families, budding readers and anyone looking for a little outdoor adventure.
