According to the BBC London web site, this weekend is International Tourist Guide Day.
Just like guides around the world, London’s Blue Badge guides will be kicking off free walks around London on the hour every hour from 10am to 3pm on Saturday and Sunday. Their walks usually cost around £5 per person, I think.
Walks will mainly start from mainline train stations such as Kings Cross, Waterloo, Liverpool Street and Victoria.
For more information, check out the Blue Badge Guides web site.
Sounds like fun. Might even have a break from my family history research and do one of these walks myself.
