The popular hobby sees participants use a Global Positioning System (GPS) enabled device and other navigational techniques to both hide and seek containers - called geocaches or caches - at specific locations marked by coordinates around the world.

"I beyond myself," Bex retrospectively declared at the beginning of her clip. "We have just found the best geocache we have ever seen. It's so good." The video then reconvened the earlier moment in which she and her partner made their exciting discovery.

Bex continued, pointing her camera at a sealed container: "You have to get the code to get in, which obviously we're not going to reveal." As her partner retrieves the key from a lock box, she adds in anticipation: "This is amazing! What do you think is going to be inside?"

Her partner proceeds to unlock the container, and following a moment of suspense, unveils a shrine to inside the right-hand door, featuring a take on the series' Book of Monsters. Opening the door on the left, meanwhile, revealed a stunning Harry Potter Lego display, featuring several builds including a Hogwarts set.

Scores of Bex' followers were equally as impressed, with one responding: "That must be the holy grail of geocaching." Another added: "Love geocaching, we have seen some amazing places off the beaten track we would never have known about! Great free family activity."

A third penned: "Oh wow that’s absolutely brilliant, I’d camp out for the next person." A fourth quipped: "Even though I detest Harry Potter I can confirm that’s got to be THE best geocache!" And a fifth hailed: "Oh wow this really is amazing I use go geo with my kids but I don't drive and did all ones we could get to so stopped.

In response to questions about the hobby, meanwhile, Bex explained: "You can do swaps with the swap box but you can’t take the stuff behind the plastic glass. You can also take travel bugs with you too. We specifically look for them so you wouldn’t know about them if it’s not something you do."
