Hauntings exist all over the world, but there are a few locations with sordid pasts and dark histories that are especially sinister and purported to be doorways to the spirit underworld.

In Travel Channel’s new series,“Portals to Hell,” premiering on Friday, April 19 at 9 p.m. ET/PT, television personality and executive producer Jack Osbourne, and paranormal researcher and investigator Katrina Weidman, join forces to explore this phenomenon, investigating each haunted location in search of irrefutable evidence that a spirit world exists, and death is not the end.

In each of the eight hour-long episodes, Osbourne and Weidman dive headfirst into a different historical site, examining unusual incidents while utilizing specialized technology and a network of experts to help document and uncover the truth. The quest for answers takes the duo to New Orleans’ infamous LaLaurie Mansion – where they are the first and only paranormal team to ever investigate the disturbing hauntings within its walls. They also investigate legendary spooky spots including Bobby Mackey’s Music World in Kentucky, Eastern State Penitentiary in Pennsylvania, the Alaskan Hotel in Juneau, Ohio’s Twin City Opera House, Strawberry River Bed and Breakfast on the outskirts of Utah’s Skinwalker Ranch, Pennsylvania’s Emerald Hill Estate and the Trans-Allegheny Lunatic Asylum in West Virginia.

“I’ve been obsessed with the supernatural ever since I was a kid,” said Jack Osbourne. “I’m excited to team up with Katrina to investigate the darkest, most sinister places on earth. We’re walking headfirst into the heart of darkness – and we’re excited to take brave viewers with us.”

“For over a decade, my work in the paranormal field has brought me to the edge of the unknown,” said Katrina Weidman. “As we explore these disturbing locations, these potential portals, Jack and I are determined to document as much as we can to try and uncover the source of these hauntings.”

“Both Jack and Katrina have great instincts for investigating the paranormal, and their passion and expertise make them a fantastic addition to Travel Channel,” said Jane Latman, general manager of Travel Channel. “The show’s unique docu-style format immerses viewers in each investigation, allowing the audience to experience every goose bump, chill and unexpected surprise right alongside the team.”
