Ngorongoro Conservation Area
The A-104 runs northward, to the west of Mount Meru, from Arusha to Longido and Namanga at the Kenyan border before continuing to Nairobi. The A-104 also runs westward past Monduli to its junction at Makuyuni with the B-144 road that leads to Mto wa Mbu and the Ngorongoro Conservation Area. After that, the A-104 curves southward to the east of Lake Manyara and continues on to Babati and Dodoma.
