A special HALF PRICE ticket offer to launch Insider London's brand new London Underground Tour

Travel across 150 years in just two hours. Moving from London's first ever Underground station to its most futuristic, unearth the remarkable stories behind the Tube's design and construction and experience its fascinating history first-hand.

A perfect choice on a winter's day, too, because as locals know, it's always 10 degrees warmer on the Underground.

Sure to fascinate and delight anyone looking to discover London through a different lens, the London Underground tour guarantees that no trip on the tube will ever be the same.

Highlights include:

• Spotting the ghost station at the British Museum
• Travelling along the proposed 'Viking Line'
• Discovering how the Victorians dug all those tunnels – by hand
• The tropical insects that live only in the Underground  
• The man behind the 'Mind the Gap' voice
• The sub-service lines forming the tube's visionary future
