In May 2025, YouTube-famous ghost hunters and urban explorers Sam & Colby published a scheduled tweet claiming they’d gotten lost in the Paris Catacombs, sending fans into a panic.
“We have been underground in the Paris Catacombs for much longer than anticipated, meaning we can’t find our way out,” the post read. “We have official people looking for us, but if you don’t hear from us within six more hours, send help.”
Thankfully, the two influencers posted an update about two hours later, showing themselves on the streets of Paris covered in grime and looking completely shell-shocked.
While Sam & Colby’s experience in the Paris Catacombs isn’t a unique one, that doesn’t make it any less harrowing. The 300 kilometers of mazelike human remains has a reputation for getting people lost, so visitors are encouraged to follow a tour guide.
Sam & Colby encountered unknown person in Paris Catacombs
Dexerto got the chance to sit down with the YouTube duo to discuss their Catacombs misadventure just three months after the incident, where they let us in on a horrifying detail they hadn’t made yet public.
They described the cramped conditions of the Catacombs during their tour, with Sam noting that the small spaces triggered his claustrophobia.
“It was one of the most physically taxing videos that we’ve ever experienced or been a part of,” Colby revealed. “There was water that went up as high as our chests, so we were completely soaked.
“…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.”
While there are numerous accounts of people getting lost in the Paris catacombs, the maze of human remains has only claimed one recorded life in 1793.
That wasn’t the scariest part of their experience, though. Colby told us that they ran into a person in the dark who wasn’t part of their small tour group — and while he couldn’t say much more for fear of spoiling his upcoming video, he said it was a wild encounter.
“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 said.
Sam and Colby aren’t the only YouTubers to have visited Paris’s Catacombs; in fact, famous YouTube star PewDiePie also went down into the depths as part of a promotion for horror film ‘As Above, So Below’ in 2014. The movie follows a group of explorers who venture into the catacombs to find the Philosopher’s Stone and end up getting more than they bargained for.
