Ruaha National Park
Ruaha is one of the more isolated parks in Tanzania. Because of this the visitor numbers are not as high, it is possible to safari for the day and not see other vehicles.
It is an ideal addition to a Selous safari or as a stand alone safari.
Its isolation means that to drive is a 2 day process from both Arusha and Selous, so I recommend flying.
Possible itinerary - Works well when visiting Selous game reserve
Day 1 - Fly from either Selous Game Reserve or Arusha. Afternoon safari drive.
Day 2 - Full day on Safari or morning sunrise safari, returning for lunch, then afternoon /evening safari
Day 3 - Full day on Safari
Day 4 - Full day on Safari - optional walking safari
Day 5 - Transfer to airfield for flight back to Arusha or Dar Es Salaam.
NOTE: A safari to Ruaha means that you will be using the Safari vehicles and guides of your accommodation, so depending upon your group size, you may be sharing your vehicle with others.
