Stay at the top with John & Kasaka tours. I strongly recommend it to you.
We opted for the 3-day formula with 2 days of safari and 1 day of hiking.
The Mikumi reserve is a beautiful reserve with many animals and above all it is not overcrowded with tourists or tour operators! We were able to see Lion, Buffalo, Elephant, Giraffe, Impala, Wildebeest, Zebra, Monkey and so on!
The hike is just amazing, very easy to get to (with family and kids no problem) for a great view of the waterfall and a view of a wonderful stretch of Tanzanian land once at the top. The guide who accompanied us was great, and will explain the virtues of the different trees that make up this forest, a part of Tanzanian history as well as the discovery of certain animals living in this forest.
The price / quality ratio is very good.
We slept at the Morio hotel, it is quite rustic but it can do the trick. On the other hand concerning the meals you will not be disappointed.
Finally to finish, John is very professional and responsive regarding exchanges by email and his tour operator deserves more attention!
