Day 1 Arusha - Olmoti Crater - Nainokanoka
In the morning you will be picked up from your hotel and after the luggage has been stowed in the vehicle, the journey will begin on a good tar road. Approaching the village of Mto wa Mbu, you can see the escarpment of the Great Rift Valley rising ahead. From a viewpoint, the Masai plains stretch up to the horizon with Lake Manyara at your feet. A short drive further, you reach the gate of the Ngorongoro Crater Conservation Area.

The journey continues with fantastic views along the crater road, until you reach the Masai village of Nainokanoka with a nearby campsite. The camp will be set up and you will climb the rim of Olmoti Crater during the afternoon. The reward of the climb is the great view that you get from the top of the crater edge. There is also a possibility to visit a small waterfall along the way. Dinner will be served at the camp. The night at 2650m height might be damply and cold, depending on the time of year.

After breakfast and loading the donkeys, the journey begins through the highland passing many traditional Masai Bomas and their cattle. After a short distance, wild animals can be seen such as Thompson and Grants Gazelle, zebras and wildebeest.

Day 3 Bulati - Empakai

The trek gives you great views of the majestic Vulcano as well as into the impressive Empakai Crater before reaching the campsite for the night. A well-maintained track goes to the crater bottom, of which one third is covered by the Empakai Lake. This (alkaline) soda lake is an important source for flamingos, which can be observed throughout the year. When returning to the camp, a good dinner will be waiting for you.
