The Haunted Mansion started as a one time Halloween activity at Kensington Water Gardens in 2001. It was such a success that it became an annual event for us every October. In 2006 we began a transition from the Kensington Water Gardens to become the Haunted Mansion as a full time business. Visitors in 2006 were polled and that told us we were going in the right direction. Operations now run from June to September for the traditional tourist season and we ramp up activities adding new scares and live actors for the Halloween - Nights of Fear! held in October.
