Ain't no mountain high enough for Jessica Biel!

The actress, 27, successfully reached the peak of Mount Kilimanjaro Tuesday after a grueling week-long climb. Situated in northeastern Tanzania, Mt. Kilimanjaro is the highest peak on the African continent at 19,341 feet.

The notable crew joining her included actor Emile Hirsch, Transformers: Revenge of the Fallen star Isabel Lucas, politician Elizabeth Gore, musicians Lupe Fiasco, Santigold and Kenna. Kenna led the all-star expedition, dubbed "Summit on the Summit: Kilimanajaro," announced in Sept. 2009 to raise money and awareness of the global clean water crisis.
