Moscow walk with enthusiasts
there is a great project of Moscow devoted enthusiasts
Protected content (site is in Russian unfortunately)
They organise (for a small fee that they donate to children hospital) very interesting walks around old Moscow that are not performed in formal tours with agencies.
If we had a grop of interested people I would ask them if they have an english-speaking guide (I believe they do have) and we might arrange a tour.
By the way they make amasing photoalbums - you can see them here in English
"Moscow: A Personal Album"
The photography of old Moscow
They publish guide-books about old Moscow also. They will show and sell them coming weekend dring Moscow b-day celebration on Bolevard Ring - Strastnoy Bolevard.
If you have any question please drope me a line here or to my e-mail
PS I have no any commercial interest in all this, I just go with them and enjoy it so concern that as my personal experience :)
