Three weeks, three countries, and three 16,000-plus-foot peaks. That's the ambitious premise behind a new itinerary from KE Adventure Travel. The trip starts with four days of acclimatization on the sharp, scree-covered slopes of 16,350-foot Mount Kenya. After summiting, drive to the Tanzania border for a five-day rapid ascent on the wild northern side of 19,340-foot Kilimanjaro. From there you'll fly over Lake Victoria, the largest tropical lake in the world, to Uganda for an eight-day trek up glaciated, 16,750-foot Mount Stanley. Don't expect posh accommodations: digs are safari tents and base-camp huts, and meals consist of mountaineer fare (porridge, coffee, pasta). Do expect some of the most remarkable views in Africa. $6,525, including park fees; July 7–30 and December 22–January 14; keadventure.com.
