Touting 45 acres of terrifying surprises, Field of Screams Maryland presents Scream City lures thrill seekers to three newly renovated, professionally designed and maintained attractions, including a 35-minute walk through a haunted forest. The multi-haunt emporium coaxes goose bumps from epidermal hideouts with movie-quality sets and props peppered throughout each attraction. Tread lightly across the unexorcised grounds of the Trail of Terror, where legends of murder, werewolves, and tax-evading butlers linger ominously behind veils of darkened forestry. The haunted halls of Lusion Manor take guests through 15 rooms brimming with jolt-inducing sights, and Hades' Hayride utilizes the unsuspecting paths of a cornfield to induce shrieks and soul-rattling cravings for popcorn.

Field of Screams' convenient location affords metro residents timely access to all three state-of-the-art haunts. Bonfires and guest appearances by local radio personalities, movie makeup artists, and celebrity proton packs also add to the scare bazaar's spirited atmosphere. Visitors can also use a $10 concession credit to refuel with a cavalcade of treats and snacks.
