I posted this question months ago, but now that the travel forums have been changed and there are many new members, I thought I would try again.

I am planning a safari to Tanzania in January 2009 (already confirmed). I'll be going to Lake Manyara, Serengeti Serena, Ndutu, and Ngorongoro. I've been to each of these places before except Serengeti Serena Lodge. What I would like to do is hike/walk with a ranger. The Ndutu web site for example, states walk in the forest with a ranger. Has anyone done that at Ndutu? How about the other places? Have you gone on a walk with a ranger in these regions? If so, please let me know about your experience,and how you made arrangements. What are your favorite hikes in these areas?

Thanks,
Roger
