If traditional history-based activities put you to sleep, or you just enjoy being given the creeps, then the London Bridge Experience is the tour for you.
It might be one of the more expensive attractions on offer in the city, but some great discounts can be made online and if you go with a group of friends, you're guaranteed to have some fun.
The tour follows the general history of London Bridge where you will learn of its many incarnations (and disasters) since its believed creation in 50 AD Roman England. You will meet characters from the Viking period, medieval London where the bridge was crammed with houses and shops, right up until the bridge's Victorian construction, designed and built by father and son team, John Rennie (senior and junior). This Victorian bridge was sold to an American entrepreneur in 1968 for nearly $2.5m and can now be found painstakingly reconstructed in Lake Havasu City, Arizona.
But however much history might be on offer, let's face it, the main thing you'll have paid for are the spooks - which, as a warning, begin when you're given a fluorescent yellow jacket and hard hat to wear (you'll understand the outfit once you proceed). So does the Experience deliver on its promised title of the 'scariest attraction in London'?
Well, the 'horror' part of the tour will certainly make you jump, whether it's from an unanticipated hiss of air, a plastic head hanging on a string (hence your headgear) or someone jumping out of a shadow or a solid-looking wall. However, from my perspective near the back, I believe the amount of times you're startled will wholly depend on your position in the line. Let's just say the people at the front of our party were screaming a lot more than those of us at the back, and that's not me trying to sound macho - I wanted to be scared!
If you're still struggling to make your mind up, consider this: does the prospect of a mad-man running at you waving a chainsaw get you shaking with a) fear b) laughter or c) mild annoyance? If the answer is a or b, I definitely recommend this tour. Even if it's c, try and take an open mind and I can promise you the London Bridge Experience will be one you won't forget in a long time.
