Manyara or Tarangire?
On a short trip, choose according to season, current conditions and the rest of your route. Tarangire often wins for a full wildlife day; Manyara can fit elegantly around a transfer to or from the Ngorongoro highlands.
Keep expectations grounded
A good guide plans Manyara around habitat and conditions rather than one famous sighting. Treat it as a varied ecosystem, not a checklist stop.
