Winter Family Trail: The Moonstone Door

About Winter Family Trail: The Moonstone Door

Escape into a world of history and fantasy with The Moonstone Door.

Thamesis and Isis are two evil sorcerers that have been set free in the museum.

Can you make your way around the museum and banish them using their own magic against them in an immersive adventure trail?

Adventurers are free to roam around the galleries and look for stations marked as a purple star on the trail card, then using the “Cosmic Lens” to figure out the hidden letter and complete the word to defeat the evil sorcerer Thamesis.

Once you have defeated Thamesis, you will receive a certificate to prove it.

This adventure is included with your General Admission ticket.

Age guidance: Suitable for children age 7 to 11.
