Before I booked anything, I spent many months researching the various companies that offer tours in Tanzania. My criteria for choosing a company included recommendations from those who I knew personally, numerous searches of reviews on Safari reviews,TripAdvisor and other blogs, the response time each company had to my emails, the willingness to incorporate all my wishes into the itinerary, etc., etc. This is the only one company was able to pass all these tests plus provide me with a reasonable cost for my 22 day trip. This trip included a 7 day Kilimanjaro trek, a 9 day safari in Tarangire, Ngorongoro Crater, and the Serengeti all the way to the Kenyan border and a 4 day journey to Gombe to visit Jane Goodall's chimpanzees and research centre.
The person I dealt with by email to book the trip, Godwin who happens to be the owner, was excellent and easy to work with. The local staff in Arusha were extremely friendly and went out of their way to ensure all was as it should be. The guides, drivers, porters and cooks were friendly in every way and experts in their jobs.
I am very happy with Touch Tanzania Tours and would recommend this company to anyone travelling in Tanzania be it a Kilimanjaro trek, a Serengeti safari or chimpanzee trekking.
