MorbidNights Colorado, Greeley

When guests cross the threshold into MorbidNights Colorado's Nut House, they enter the tormented minds of history's most notorious serial killers. Inside the 20 rooms that occupy the 12,000 square-foot fear factory, brazen voyagers come face to face with some of the most homicidal humans ever to walk the earth, and shudder with fear as the criminals reenact their notorious crimes or a favorite dance number from South Pacific. Those brave enough to risk the madness do so for a great cause, however, as the haunt donates a portion of its yearly proceeds to worthy causes including the Weld Food Bank or UNC student radio.
