Doctor Evil's House of Horrors, Guerneville

Dr. Evil was born to a Russian scientist during the height of the plague that stole his mother in 1771. To this day, the immortal Dr. Evil carries on his father’s gruesome experiments—stopping at nothing to find a body that can host his dear mother’s soul, which his father preserved in a metal box.

For this year's new theme, adventurers explore the doctor’s House of Horrors, wandering amid blood-soaked halls that teem with the insane and demonic, including doctors vivisecting their patients, clowns in hastily smeared makeup, and a disgusting man returning from the bathroom without washing his hands. Live actors hiss and scream at the interlopers as they step across uneven flooring, press on through rooms coated in spiderwebs, and twist and turn through fog. Victims too young for the main attraction are invited to the free, kid-friendly fun house.
