A cheaper alternative to hiking Kilimanjaro, you can climb Mount Meru within the span of 2 to 4 days. There is no need of guides or porters to Meru. However, you may need to be escorted by rangers. Temperatures often reach freezing points, and therefore, it is important to be ready in warm clothes and sleeping bags.
Cultural excursions: The Tanzania tourist board holds excursions to nearby villages. The trip is worthwhile especially because of the human cultural element that exists in them.
