Cosiano safari custom tailored a 5 days 4 nights safari for us which was outstanding
The 5 days included Tarangire Np, Serengeti Np (2 days), Ngorongoro crater Np and Arusha mount Meru.
My wife and I were alone in the car with our guide Ali, car which could have fitted 8 people. So we had plenty of space. The lodges were outstanding and above our expectations.
The guide Ali knew everything about plants and animals, birds etc. We could not fault him.
He also had an excellent command of English.
As far as animals are concerned, we saw them all multiple times except rhinos and leopards for which you also need a bit of luck. But we saw 3 cheetahs and many lions.
I highly recommend Cosiano Safari and the guide Ali.
We organized our safari in Zanzibar and flew back and forth.
It was excellent value for money, way cheaper than we had checked in the internet beforehand.
