As a newer route, it is more remote and arguably more beautiful, but a bit longer and slightly more expensive. It starts on the Western side of the mountain at the Londorossi Gate which is a further drive from town, and was introduced as an alternative to the Shira route.
After beautiful forests and moorlands it crosses the Shira Plateau on day 3 to connect with the Machame Route at Lava Tower and down towards Barranco Valley via the Southern Circuit. You may be lucky enough to see buffalo, elephant and other game. Because this route can be done over a longer period of time for acclimatization, it has a higher success rate of the summit.
