I am a Kenyan now living in the US and planning to visit Tarangire with my friend either mid-January or mid-February. I am a very experienced Africa traveler, and we are looking for the absolute cheapest way to see Tarangire, Ngorongoro and Lake Natron. We are not interested in luxury at all - basic camping, simple food, will do, but we need transport, park entrance etc. Anyone else done this? I know I should use local companies based in Moshi or Arusha, but there are so many, it's impossible to choose without some advice. Companies from abroad are way too expensive. We can spend about 5 days there. All tips and suggestions are welcome.
