Hillary Baraka our Safari guide and driver picked us up at Kilimanjaro airport. He was extremely accommodating, excellent communication in English and listened to our desire from the trip. 3 of us (a couple and myself) wanted to stop in Arusha to pick up food before the hotel, he was kind enough to call and place the order thus extremely accommodating to our needs.
During our few days with him, he knew every part of Serengeti, found out thru CB radio where the animals were and got us to the spot so we could get some good pictures. He helped us experience 3 kills, 1 stand off with lions and all the big 5.
I highly recommended Hillary as your guide if you are planning to take the Safari. Ride with someone who knows Serengeti National park's every corner of it. I personally will request for him next time I go for Safari.
