We encourage you to wear light khaki, olive, tans and brown/beige as they increase the chances of better game viewing. However, due to the high altitude on the rim of Ngorongoro Crater, night time temperatures are cold even in summer. Travelers to these regions should pack a fleece or sweater, as well as a warm jacket for game drives. Swimwear is a must when traveling to the coastal areas of Zanzibar. Comfortable walking shoes are essential for those planning bush walks or walking safaris. Guests intending to climb Mount Kilimanjaro and Mount Meru should pack thermal underwear, light layers, a sweater, warm jacket, good socks, and sturdy boots.
