Review about Mikumi National Park by Stuart
This park has the usual range of African wildlife - lions, elephants, giraffes, and so on. Unusually, the (unserviced) camp sites are unfenced, so think twice before venturing out of your tent at night! There are also more luxurious accommodation options for the less brave. The park is large and not commonly visited, so you may well have the place to yourself - a nice change from some of Tanzania's busier parks.
Review about Arusha National Park by Stuart
I visited the park to climb Mount Meru and do a game walk or two. Walking through the bush with buffalo nearby is an unreal experience (you are accompanied by an armed ranger). The climb to Mount Meru's summit is quite tough, but there are good cabins along the way which are warm and well kept. Spectacular views from the park including the sun rising behind Kilimanjaro.

Stunning
Our visit to Buffalo Springs NP.
In september 2011 we visited Buffalo Springs NP in Kenya.
We drove in an open Safari truck so we had a good sight at the different kind of animals that you normally only see in a zoo.
The nature is great and it is quiet because there're not so much tourists as in other NP's. The roads are unsealed but the trip was not too uncomfortable.
We saw a lot of animals but also a lot of birds and that's fine for a birdlover like me.
Highlights are the Lions and a Leopard with its kill in a tree.
We saw p.e.; Lions, Leopard, Gerenuks, Grant's Gazelles, Kirk's dik-dik's, Reticulated giraffes and Gemsboks.
We also saw a lot of birds, like; Yellow-necked spurfowl, White-headed Buffalo-weaver, White-browed Sparrow-weaver, Lilac-breasted roller, Rueppel's long-tailed starling and Brown snake-Eagle.
The Acacia trees and Doumpalms are beuatiful and you can visit a village of a very friendly Samburu tribe.
I'm glad that we have seen this NP and recommend it.

Review about South Africa by galago1962
Huge variety in parks, animals, scenery. High level of hospitality.
Beautiful country with a wide variety of safari options
Tanzania has many safari options, from luxury hotels in the heavily visited Ngorongoro to unserviced campsites in Mikumi National Park. In general the main roads outside the cities are OK but other roads are often dirt. However, in my experience safari companies are well aware of this and bring appropriate transport (as always, you get what you pay for).
Tanzania has some unmissable sights: Ngorongoro, Serengeti (an extension of the Mara in Kenya) and, if you are fit enough, climbs up Mount Meru and Kilimanjaro.
Safari options range from basic camping (in parks where it is allowed) to all-inclusive luxurious hotels in the middle of the savannah. Often it is a good idea to get a park ranger to accompany you if available - they often offer - and because they work in the park all the time, they can be more knowledgeable about recent animal sightings.
If you are visiting the parks in the north of Tanzania you probably won't have much reason to visit Dar es Salaam, and you probably won't miss much either. It isn't a particularly interesting place and many people just pass through on the way to Zanzibar.
