Watch Ghost Adventures Online - Full Episodes

Travel Channel's "Ghost Adventures" is a paranormal investigation television series featuring Zak Bagans, Aaron Goodwin and Nick Groff. Ghost Adventures host Zak Bagans narrates each episode. Ghost Adventures has visited famous haunted residences with dark histories such as the home of the axe murderer Lizzy Borden, the Winchester Mystery House and the Peabody-Whitehead Mansion where potentially dangerous ghosts have been reported and are thought to be extremely active.

Each episode, the investigators head to a haunted location where they interview eyewitnesses and speak with local historians and building caretakers. After gathering information about the area's history, they lock themselves in the building overnight, from sundown-to-sunrise, during a time that they refer to as "lock-down." During lock-down, host Bagans uses aggressive methods to evoke ghosts by verbally assaulting them, which he believes causes the ghosts to become angry enough to make their presence known.

While investigating, the three men explore the location and attempt to capture evidence of ghosts reported to haunt the area with night-vision cameras, audio recorders, electromagnetic field meters, digital thermometers and a device called the Ovilus. The Ovilus takes temperature and EMF readings, adds them together and uses the number to pick a word from a database, which it says out loud.

After lock-down, they analyze the spirit photos, electronic voice phenomena and video footage of ghosts that they recorded and use it to prove that the location is haunted.

The award winning "Ghost Adventures" TV series is based on a documentary of the same name that aired on the Sy-Fy Channel in 2007. Previous guest investigators include Vince Neil, Chad Lindberg and Bruce Westcott. In addition to the regular episodes, "Ghost Adventures" also features one-hour specials such as Ghost Adventures Live: The Trans-Allegheny Lunatic Asylum, Best Evidence and Scariest Moments.

"Ghost Adventures" premiered October 2008. As of July 10, 2012 filming of the show's seventh season is currently underway. The seventh season will air on Travel Channel in the fall of 2012.
