In a nutshell. You’re in a cave. On a boat. You float past tableaux and sound-and-light shows that bring Celtic Britain and Arthurian legend to life. There’s also the occasional dragon – not forgetting the underground waterfall.

Why go? Below ground is just the half of it. Back on the surface there’s more legendary storytelling on the spooky paths of the Bards’ Quest, and shopping at the Corris Craft Centre. And you can go underground for the second time with Corris Mine Explorers.
