Climb Kilimanjaro on the Rongai route used to guarantee you a quiet trek away from the masses. This route is marketed as a remote wilderness experience and for much of the year it still is. However in the couple years Rongai has seen a surge in popularity. If you climb Kilimanjaro on the Rongai route during the main season (August to mid October) and if your climb starts on the usual group departure day, you may find yourself in the middle of a pretty big crowd. Rongai is the easiest route up Kilimanjaro, in some respects easier than Marangu. Rongai has excellent success rates. Rongai is the only route that approaches Kilimanjaro from the north. You have to descend on the Marangu route on the southern side, so you get to see both sides of the mountain. The northern side of Kilimanjaro is drier. You are unlikely to have to slosh through mud and drizzle on the first two days.
