Northern Circuit The longest and the newest route on Mount Kilimanjaro, Northern Circuit, is known for excellent acclimatization and breathtaking views of the Kilimanjaro northern slopes. For the present moment a very limited number of travelers have set foot on this trail, and the route is hardly ever crowded. It is recommended to those who enjoy long trekking experiences in remote wilderness with a minimal number of other trekkers around. It takes at least eight days to climb Kilimanjaro through the Northern Circuit which is why the route boasts a very high success rate. A 9-day extended version with crater camping is also available for an incredible wilderness adventure on Africa’s highest volcano.
