North-east of the Ngorongoro Crater lies the Empakaai Crater. Empakaai is about 6000m wide and 300m high.
Among other animals, you will see buffalo, bush buck, a variety of antelope, and blue monkeys. Birds are in abundance too. A deep soda lake covers a large part of the crater floor. There is a track to the crater floor and one around the rim of the crater. On a nice, clear day, one can see Mt. Oldonyo Lengai, Lake Natron and Mt. Kilimanjaro. The scenery is left to your imagination.
Olmoti Crater: Close to the Nainokanoka village, also North-east of the Ngorongoro Crater, lies this sunken caldera. A visit to Olmoti is only possible by foot with an armed ranger escort. It takes about 35 minutes to walk to the rim of this shallow crater. Lots of different species of antelope can be found here. A walk to the waterfalls of the Munge River is also interesting.
