Things to Do in Eastchester

Timothy Haskell is no stranger to scaring folks: The Daily Beast considers his Nightmare series "one of the most frightening haunted-house productions in New York City." But when he teamed up with haunted-house vet Steve Kopelman, Timothy didn't want to keep populating creepy corridors with imaginary ghouls. At Nightmare: Killers, the duo tap into the true terror inspired by historical and contemporary serial killers to explore the monstrosity of their actions and the celebrity and cultural obsession surrounding them. The New York Times lauds the attraction as “a taut, assured production that knows exactly what it wants to do (scare the hell out of you) and performs its task with ruthless, coldblooded precision."

In the lobby, a gallery of artwork, memorabilia, and items from or about famous serial killers primes guests on the haunted attraction's theme and provides a glimpse into the warped minds of the killers in question. At the front of the line, personnel can mark any willing visitor’s forehead with an optional scarlet X, which will grant the actors permission to interact with those victims for the next petrifying 20–25 minutes. Inside the haunt, rooms depict scenes based on Ted Bundy and the Zodiac killer, with the occasional cameo from pop culture’s most fearsome fictional figures. To heighten heart rates even more, visitors will also have to navigate twists and turns, fog, and uneven footing as they desperately try to avoid becoming each psychopath’s latest victim.

Located inside the Poughkeepsie Galleria, Vendetta Paintball and Laser Combat challenges players to technologically advanced games of laser tag and paintball on a 22,000-square-foot indoor field. Designed to mimic live-action games of Call of Duty or Halo, Battlefield Live laser tag manufactures adrenaline with real-time hit feedback, realistic special effects, and equipment that can simulate 69 different weapons, ranging from AK-47s to banana-cream pies. The facility’s professional-grade indoor PSP paintball field lets gamers improve their hand-eye coordination while simultaneously turning rivals into walking tie-dyed targets.

Under the bright lights of the world-famous Madison Square Garden arena, four of the best women’s college basketball teams in the country will tip off in the Maggie Dixon Classic. The first game pits Baylor against St. John’s before DePaul takes on Tennessee to guess the number of jellybeans hidden inside the basketball. The undefeated Baylor Bears, ranked No. 1 in the nation nine games into the season, follow the lead of junior slam-dunk machine Brittney Griner. Pumped up from her placement on the Naismith Trophy early-season watch list, St. John’s senior forward Da’Shena Stevens will induce frustrated growls from Baylor as she makes them work for their points. With 15 NCAA Tournament appearances in the last 23 years, DePaul’s squad enters the high-pressure match gracefully, and Tennessee confidently follows the lead of its celebrated coach, Pat Summitt, named Sports Illustrated’s Sportswoman of the Year for her more than 1,000 wins and ability to slam dunk while riding a unicycle.

The phosphorescent, indoor landscape at Monster Mini Golf immerses putters in an eerie universe that inverts the sun-soaked cheer of conventional courses. Rimmed in glowing green barriers, 18 holes lure swingers of all sizes to challenge their coordination and resolve in the face of winged monsters, scowling animated trees, a creepy clown, and their opponents' shockingly dazzling smiles. Sheltered from searing rain and howling wind, the indoor course enables play around hazards such as a spell well and luminous, ghostly windmill at any time of the year. An in-house radio station and DJ mask the sound of pounding hearts with lively beats and course commentary, and golfers looking for additional glory can win prizes by participating in regular contests or at the onsite arcade (arcade games not covered by this Groupon).

Helmed by a team of passionate climbing coaches, both of The Gravity Vault's locations surround climbers with more than 13,000 square feet of climbing space. Walls tower past 35 feet, mimicking such natural rock formations as overhangs, keyhole arches, and slabs, and bouldering areas challenge climbers with a latticework of problems that—unlike most of life's—can't simply be solved with dynamite and a pair of roller skates. Visitors can choose from up to 60 top-rope stations, trusting either the trained staff or a certified fellow climber to man the ropes while they scramble to the summit. When not dangling from a hold or saving lost kittens from a rappel ledge, members can bulk up in the cardiovascular-training area.
