In celebration of the 2012 Summer Olympics in London, Travel Channel is premiering two all-new special episodes of "Ghost Adventures" on Friday, July 13 and Friday, July 20 at 9:00 p.m. ET/PT. The crew - Zak Bagans, Nick Groff and Aaron Goodwin - travels to England to investigate two of the country's most haunted and terrifying locations: the Hellfire Caves (airs July 13) and Fort Horsted (airs July 20).

The trio interviews eyewitnesses and historians at each location, arming themselves with the stories of the ghosts they later confront during the dusk-to-dawn lockdowns. After each lockdown, they review and analyze their findings with some of the most respected experts and specialists in the paranormal field.
