A safari to Lake Natron is unique.  Lake Natron is a breeding place for Flamingos. It is the largest breeding place in the whole of East Africa.The nests are are constructed on the islets located in middle of the shallow lake. The idea is to  keep them safe from egg eaters. Unless by air, the eggs and the young birds are unreachable.   While enjoying the colorful flocks of the flamingos, there is a sight of  a dormant volcanic Mt Oldoinyo Lengai. It take one night to get up there and come down.  It last smoked in 2009. Natron river, oh yes, another attraction. Trekking along the sloppy rocky sides of the gorge all the way to Natron waterfalls, that is another entertainment of its kind.
