Rongai Route
The Rongai Route is the only route that starts from the north side of the mountain, close to the Kenyan border. Though gaining popularity amongst climbers, this route still experiences fewer climbers. Rongai has a more gradual slope than the mountain’s other routes. It is the preferred route for those looking for an alternative to the popular Marangu route, for those who would like a more remote hike, and for those who are climbing during the rainy season (the north side receives less precipitation). Rongai is a considered by some as the easiest route and is highly recommended, especially for those with less backpacking experience.
Although the scenery is not as varied as the western routes, Rongai makes up for this by passing through true wilderness areas for nearly the entire way. Descent is made via the Marangu Route. Although Marangu Route has huts, those who are descending from the Rongai Route will spend overnights in tents.
Claris Tours and Travel offers Rongai as a six or seven-day climb. The six-day variation does not have an acclimatization day on day four at Mawenzi Tarn.
