After breakfast, we walk a short way around the Empakaai crater to stretch our legs and get some good panoramic photos of the caldera. The first half of the trek is to Nayobi village where you will stop for lunch. From Nayobi we head down to Acacia Campsite. You will head out on a late afternoon walk to view the surrounding area and take photos of the majestic Mt. Ol-Doinyo Lengai, a Maasai name for the “Mountain of God”. This mountain is unique amongst geologists because it is the only active volcano on Earth that erupts with carbonatite, a type of igneous rock rich in carbonates such as calcite and dolomite.
