I´ve been warned about robberies on Mt Kenya by travelers who have"heard stories of it", but can´t find anything when I google, and when I asked the park service they said they had had no problems (not that I would trust their word for it, since it´s in their interest to keep people coming there). There are three of us, and we don´t plan on using a guide or porters, and we are taking the Chogoria route to Point Leana in July.

Cheers

Use common sense and for travel anywhere, visitors are always advised to stay clear of crowds, especially those that might be demonstration for one reason or another. It's not usually for there to be a demonstration anywhere in any country that those not involved have any inkling it's happening.
