Kilimanjaro Is Climbable All Year Round. The Best Months To Climb Are December-March, And September-October, Which Are The Warmest And Driest Months. The Next Best Are June To August, But They Are Colder. July, August, And September Are The Busiest Months. Summiting On Or Soon After A Full Moon Is Very Beautiful And Helps Illuminate The Landscape Without Using Headlamps. However, It Is Also Very Bright For Sleeping And Stars Are Not As Visible.
