The trip runs ten nights in northern Tanzania and turns on a single climb. It opens with two nights at Ngare Sero, on the forested slopes of Mount Meru near Arusha, then takes the Lemosho route up Kilimanjaro: forest, the Shira Plateau, the Barranco and Karanga valleys, and Barafu below the summit. From Barafu you reach Uhuru Peak and descend to Mweka.
You climb on foot with a supported team, moving camp each stage and gaining height gradually to acclimatise. The days build from forest to plateau and high ground, then the summit and the long descent. On the mountain you sleep in camps set up and struck as you go; Ngare Sero, a small 1905 farmhouse the Leach family has run since 1974, bookends it.
