Expedition Unknown Season 16: Josh Gates Explores the Great Pyramid of Giza in a Thrilling New Premiere

The adventurer returns with exclusive access to one of the Seven Wonders of the Ancient World

Josh Gates is back — and this time, he’s heading deep beneath the sands of Egypt. In the Season 16 premiere of Expedition Unknown, the globe-trotting explorer gains exclusive access to the Great Pyramid of Giza, one of the most enigmatic and awe-inspiring structures on Earth.

Unlocking Egypt’s Greatest Mystery

In this week’s episode, Gates tackles one of history’s most famous and fiercely debated questions: What secrets still lie hidden inside the Great Pyramid?

As he crawls through narrow tunnels and ancient passageways, Josh investigates a labyrinth of hidden chambers in search of the lost tomb and treasure of Pharaoh Khufu — the ruler believed to have commissioned the Great Pyramid over 4,500 years ago.

Along the way, he dives into the wild conspiracy theories surrounding the pyramid’s origin and purpose — from alien architects to advanced lost civilizations — separating myth from evidence with his trademark mix of humor, skepticism, and scientific curiosity.

“Getting to explore these spaces few have ever seen was an absolute honor,” Gates teases. “It’s one thing to study the Great Pyramid; it’s another to crawl through its hidden heart in search of answers.”
