I'm one of the only fully qualified black female tour guides in London. I have a website called Avril's Walks and Talks and that's where you can find out all about my walks and talks that I do around London. You can also contact me on firstname.lastname@example.org to find out when the walks are.
Walks run from March/April to October and usually cost in the region of £10 per person (though this is likely to change as and when).
My walks are very popular and I have worked for people such as the MOD, the Lord Mayor London and I also do lots of private walks for tourists (mainly America) and people who live in London. This is the Hyde Park Walk with a small group (that's me in the purple puffer jacket).
