UNIVERSAL STUDIOS in Orlando, Florida, puts the fun in fear by creating elaborately haunted Halloween habitats on its five themed islands. For 21 nights in October and early November, daring visitors can venture into spooky settings where mutant dinosaurs mingle with demons and twisted footpaths lead to foreboding places. The park’s rides, thrilling by day, become even more chilling at night — operated under the cloak of darkness, and under the guard of unruly creatures. With dimly lit mazes, live shows, and dozens of unexpected frights, it’s no wonder they’re called the Islands of Fear. (877) 237-4448, www.halloweenhorrornights.com
