A great, great experience
My son and I did the 6 day Rongai route with Original Tanzania established in Moshi. We booked directly with them through the internet. We enjoyed having a private trek (we were only 2 climbers) which allowed to enjoy the nature at every moment and to have a lot of discussions with the crew. The good feeling of the guide allowed reaching the summit in very good condition. A great, great experience.
As Original Tanzania suggested, we did a (private) safari before the climb instead of after. So, you are not too tired at the start the Safari. After a coffee tour and the waterfalls in the Materuni Chagga village, we went to Lake Natron where we climbed the Ol Donyo Lengai (with amazing sunrise at the summit) and met the Maasai people. After this we visited the north and center Serengeti, the Ngorongoro and Tarangire National Parks where we had a lot of early morning game viewing. The nature is yours… We saw the Big 5, the Ugly 5! and the others.
We recommend the Original Tanzania team, in particular if you prefer a tailor made itinerary or if you want to feel the nature, the people and the Tanzanian culture.
