Since January 2015, explorer Josh Gates has been on a relentless quest to crack the world's most stubborn mysteries. Expedition Unknown follows Gates as he chases legends, from lost cities and sunken treasure to cryptids and ancient artifacts, turning dusty folklore into hands-on detective work. With 19 seasons and 290 episodes under its belt, the show blends documentary rigor with reality-TV energy, all wrapped in Gates's trademark wit and a genuine sense of wonder.
The format is simple: pick an unsolved story, hit the road, and see what turns up. Gates doesn't just narrate from a studio. He dives, climbs, digs, and negotiates his way through jungles, deserts, and war zones, often with local experts and historians at his side. The tone stays light and adventurous, even when the subject matter gets heavy, and Gates's knack for deadpan humor keeps the pacing brisk.
Critics and audiences have responded warmly, with an 8.0/10 IMDb score from over 2,300 votes. The show has become a staple for armchair adventurers, proving that the thrill of the hunt never gets old. It's part travelogue, part history lesson, and part buddy comedy, all rolled into one globe-trotting package.

Expedition Unknown premiered on Travel Channel on January 8, 2015, and quickly carved out a niche in the adventure-documentary genre. Host Josh Gates, an archaeologist by training with a quick wit and an insatiable appetite for adventure, travels the globe investigating enduring unsolved mysteries, legendary lost cities, buried treasures, and puzzling historical enigmas. The show's premise is straightforward: pick a story from history or folklore that has defied explanation, hit the road, and see what turns up. Gates does not narrate from a studio; he immerses himself fully in each expedition, diving, climbing, digging, and negotiating his way through jungles, deserts, oceans, and even war zones, often accompanied by local experts, historians, and scientists.
The central character is Gates himself, whose archaeological background, deadpan humor, and genuine sense of wonder anchor the series. Each episode typically follows a structure where Gates investigates the latest developments in a particular legend, consults with experts, and then embarks on a fully immersive exploration to separate fact from fiction. He inserts himself into different cultures to understand the world as they do, whether trekking through Fiji in search of Amelia Earhart's remains, diving the deep seas of Panama to locate Captain Morgan's pirate ship, or excavating ruins in search of the real Robin Hood.
Season 1 (2015, 12 episodes) established the format with iconic mysteries like Amelia Earhart and Captain Morgan. Season 2 (2015, 19 episodes) expanded the scope, taking Gates to Nepal's "sky caves" in search of Shangri-La and investigating Christopher Columbus's voyages. Season 3 (2016, 17 episodes) tackled questions like the identity of D.B. Cooper and the location of Captain Kidd's lost treasure and Attila the Hun's tomb. Season 4 (2017, 10 episodes) explored Viking history, the mystery of Stonehenge, the lost tombs of the Mayan Snake Kings, and the hunt for twelve buried treasure boxes hidden in America.
The show made a significant transition in 2018 when it moved to Discovery Channel, debuting with Season 5 and a two-part quest to the lost city of El Mirador deep in the Guatemalan rainforest. Season 6, subtitled "Search for the Afterlife," was a four-episode arc investigating the spirit world and questions about what happens after death, from ghost hunts to ancient medicine practices. Season 7 in 2019 featured Gates following in the footsteps of the real Indiana Jones to learn the truth behind the fabled Crystal Skull of Doom and diving the Great Lakes in search of the lost shipwreck The Griffon, with a two-hour live event from Egypt kicking off the season.
Subsequent seasons continued the pattern of globe-trotting investigations. Season 8 (2019, 13 episodes), Season 9 (2020, 8 episodes), and Season 10 (2021, 6 episodes) maintained the format through the pandemic era. Season 11 (2022, 14 episodes) marked a return to fuller production schedules, while Seasons 12 and 13 (both 2023, 8 episodes each) continued exploring everything from ancient civilizations to modern mysteries. Season 14 (2024, 7 episodes) and Season 15 (2024, 6 episodes) kept the momentum going, with Season 16 (2025, 8 episodes) and Season 17 (2025, 6 episodes) bringing the series into its current era. The show's 18th season premiered in 2026, and the series continues to return with new episodes, having been renewed repeatedly due to strong viewership.
