Arusha National Park usually works best as a first safari day, a short nature-focused add-on or a gentle start after arrival before continuing into Tanzania's larger safari areas.
Many travellers use Arusha National Park as their first safari experience because it is close to Arusha town and Kilimanjaro Airport. The shorter transfer, green scenery and walking safari options make it easier to ease into the rhythm of safari.
It is not usually a replacement for Serengeti, Ngorongoro or Tarangire, but it adds variety. It works especially well for travellers with an extra day before the main route, families who want shorter drives or hikers considering Mount Meru before Kilimanjaro.
