Deep in the bowels of London Bridge is the country's scariest attraction.

This Halloween, if you want your adventures dripping with blood guts, gore and special effects, it's the only place to go.

So leave the kids at home and journey into London's darkest secrets? Here's all you need to know...

Where is it?

Phobophobia: Terror Nights are in the world-famous haunted London Tombs. Part of the London Bridge Experience, the attraction is in Tooley Street, SE1. The Terror Nights run until October 31 from 6pm to 10pm.

Who says that it's scary?

Well, we do as we checked it out last week. However, if that's not enough, it's been crowned UK’s Scariest Attraction for nine years in a row and also the Best Horror Attraction in the World. That's some recommendation.

What's the story?

London Tombs has a long history and a sinister past, and you'll come face to face with most of it as you journey deep into the maze. Among the residents are a horde of lost souls, survivors of the plague pits, maniac butchers and killer clowns - all forever stuck within a nightmare under London Bridge.

Tell me more...

A unnerving trip into your worst nightmares, to get the best out of the attraction groups of five are recommended. The bigger the group the smaller the surprise. The traumatic trip lasts around 30 to 45 minutes depending on how fast you want to get out. Tickets cost around £28, but if that price is a tad to terrifying, search around as various online deals are available.

Who can go?

Anyone over 16 - and who doesn't scare easy. If you're a family and have younger kids, tickets for all ages are available from 10am to 5pm to the London Bridge Experience and London Tombs. Book at www.thelondonbridgeexperience.com

How to get there

The attraction is just a two-minute walk from London Bridge tube and mainline station. If you want to make a full day of it, the attraction is alongside Borough Market - or why not take in the amazing view from The Shard, the UK's tallest building that's just down the road?
