Sam & Colby Share Terrifying Experience in Paris Catacombs

In May 2025, YouTube personalities Sam & Colby found themselves in a precarious situation while exploring the infamous Paris Catacombs. The duo sent a tweet to their followers, expressing their distress after becoming lost underground. “We have been underground in the Paris Catacombs for much longer than anticipated, meaning we can’t find our way out,” the tweet read. They urged fans to notify authorities if they did not hear from them within six hours, adding a sense of urgency to their predicament. Fortunately, just two hours later, they provided an update, sharing a video of themselves reemerging onto the streets of Paris, albeit covered in dirt and visibly shaken.

The Paris Catacombs, which stretch approximately 300 kilometers, are known for their labyrinthine layout and the skeletal remains of over six million people. Given the complex nature of the tunnels, visitors are typically advised to explore the site with a tour guide. The duo’s experience, while not unique, highlights the dangers of navigating these ancient passageways alone.

Inside the Catacombs: A Harrowing Adventure

Three months after their harrowing adventure, Sam & Colby spoke with Dexerto about the challenges they faced during their journey. The cramped conditions of the Catacombs proved particularly daunting for them, with Sam admitting that the tight spaces triggered his claustrophobia. “It was one of the most physically taxing videos that we’ve ever experienced or been a part of,” Colby explained. He described how they encountered water levels reaching their chests and had to crawl through narrow passages. “There were multiple tiny holes we had to crawl through, even part of a cave where we had to army-crawl half a football field’s length to get to one of the bone rooms,” he added.

Despite these discomforts, the most unsettling part of their journey occurred when they encountered an unknown individual in the dark. Colby hinted at the mysterious encounter but refrained from revealing too much to avoid spoiling their upcoming video. “We did run into somebody down there that wasn’t part of our group. I don’t want to spoil what happens there, but it was a crazy experience,” he remarked.

The Legacy of the Catacombs on YouTube

Sam & Colby are not the first content creators to navigate the eerie depths of the Paris Catacombs. In 2014, renowned YouTuber PewDiePie explored the same site as part of a promotional effort for the horror film As Above, So Below. The film follows a group of explorers searching for the Philosopher’s Stone, only to confront terrifying challenges along the way.

While the Catacombs attract thrill-seekers and history enthusiasts alike, the experiences of Sam & Colby serve as a reminder of the potential dangers that lie beneath the city. Their unexpected adventure not only entertained their followers but also highlighted the importance of safety when exploring such treacherous environments.
