Day 4: Horombo Hut (12,155ft/3705m)
Spend a rest day at Horombo Hut. To acclimate to the altitude, head out on a day hike to Zebra Rock, a geologic phenomenon in a beautiful setting. Don't forget to check out the star-covered sky. With almost no light pollution, the mountains are an astronomer's paradise.
Day 5: Horombo Hut to Kibo Hut (15,518ft/4730m)
The hike continues through yet another microclimate, the alpine desert. This moon-like landscape gives you great views of the summit. Reach Kibo Hut for some rest before heading out that same evening for your final ascent.
