Hi,
A bit late to post to your question for the Aug 2010 trip, but info for anyone else going to Ruhija to track gorillas nonetheless! I stayed at Ruhija Gorilla Friends Resort Campsite there, run by a young girl named Josephine. I just took a bus from Kampala to Kabale, where we found a driver from the bunch of young men looking to offer transport. There isn't much of anything in Ruhija, so if you want to bring food for your lunch while trekking, might be a good idea, or snacks/beverages. The driver took us to a grocery store, called ahead to Josephine, who prepared dinner for our arrival and also stayed the night at the lodge to drive us back the next day ($50 each way for the driver but we didn't have to pay his accomdations for the night). The campsite resort isn't exactly a resort, but quite nice nonetheless. We stayed in a tent with double bed inside, quite cozy with a veranda overlooking the mountains of Uganda and the Congo. Josephine's # is 0783411533, and the owner's # is 0772480885 - they would be delighted to have you! Happy Trekking, enjoy!
