In reply to nutme:
I am a Russian speaker, and have lived in Chita and Voronezh in the past, so information in Russian would be great.
I'm not keen on getting a guide if we can avoid it, I guide groups in the Scottish mountains and I don't think I would be very good at being guided!! I like to make the decisions!
I can probably sort transport, we have a friend in Moscow who is likely to want to join us and he has a car.
It's really guide books, suggestions of the best areas to base ourselves, and recommendations of favourite routes. (Walking or climbing, open to all suggestions).
Where are your from, Nutme?
