Really enjoyed ourselves - Peter, our guide, provided lots of great info about the Underground. Even though the system was quite crowded - apparently everyone was out and about riding the tube, due to it being a beautiful Easter Sunday - they provided receivers and earphones so it was quite easy to hear him throughout the tour. Wish we'd been able to go into one of the old abandoned stations (apparently available on another tour), gotten more current operating info (# of lines, miles of track, # of employees, costs, # of trains, speeds, etc. - probably just interesting to me) and had the opportunity to ask more questions but would still highly recommend the tour.

A must do on a visit to London. We have been on the tube many times, This tour opens your eyes as to what you are missing as you rush from place to place with the hussel and bussel of the city. Many unknown facts, some funny, some shocking and always entertaining. It was great to travel on the oldest line and the newest line...on the underground. Thank you so much.

The Guide was knowledgeable and interesting. I thought the "secrets" would involve actually get to see inside a disused station - I should like to have seen the underground bunkers built to shelter citizens during the war but understand that is not possible. The history of the underground is very interesting and the guide included general stories which added to the experience.
