SUBTERRANEAN SPINE-TINGLER: The London Tombs make up the far creepier half of the two-part London Bridge Experience and is a repeat Scare Award–winner for the U.K.’s Best Scare Attraction. Brave guests are ushered into a network of underground vaults where zombies, ghouls and state-of-the-art animatronics await in the darkness to frighten them silly. A milder “Guardian Angel Tour” through the London Tombs is recommended for children under 11. www.thelondonbridgeexperience.com

JOLLY GOOD GHOST TOUR: Board a red, 1960s Routemaster double-decker bus near Trafalgar Square and hit major sights like  Westminster Abbey, the Tower of London and St. Paul’s Cathedral — but with a Halloween-ish twist — during London’s Ghost Bus Tour, driven by guides in character who share each site’s grisly past. www.theghostbustours.com

LOCAL PUB WITH A HAUNTING HISTORY: Tucked on a quiet side street in London’s ritzy Belgravia district, the unassuming Grenadier pub is named after — and reputedly haunted by — an 18th-century soldier from the Duke of Wellington’s army who was killed in the basement after getting caught cheating at cards. Back then, the property was an officers’ mess for the Duke of Wellington. Today, it’s a decent spot to drink Old Speckled Hen and hear regulars yarn about ghostly encounters with “Cedric,” the card-cheating cad. www.taylor-walker.co.uk/pub/grenadier-belgrave-square/c0800

FEARSOME FARM ATTRACTION: On select evenings through Nov. 2, Tulleys Farm, a working farm about 30 miles south of London in Crawley, morphs into Tulleys Shocktober Fest World Famous Scream Park. There’s a haunted cornfield, horrifying hayride and other after-hours Halloween attractions that are way scarier than even Brussels sprouts. www.halloweenattractions.co.uk/shocktoberfest

BONUS LATE-OCTOBER EVENT: Yeah, we know: American football isn’t nearly as big as British football on the global stage. But on Sunday, Oct. 27, when the Jacksonville Jaguars play the San Francisco 49ers at Wembley Stadium in the seventh-annual NFL International Series before a rabid English fan base, one might be fooled. www.wembleystadium.com/events.aspx
