There are two typical constructions: you can say 'eine Safari machen' (to go on/do a safari; verb + accusative object) or 'auf Safari gehen/sein' (to go/be on safari; prepositional phrase without an article). Both are very common.
Nächstes Jahr wollen wir eine Safari in Tansania machen.
Next year we want to go on a safari in Tanzania.
The most common combination is 'eine Safari machen' (to go on/do a safari). The place is often mentioned too, for example 'eine Safari durch den Nationalpark' (a safari through the national park) or 'eine Safari in Afrika' (a safari in Africa).
Eine Safari durch die Serengeti ist ein unvergessliches Erlebnis.
A safari through the Serengeti is an unforgettable experience.
The figurative meaning of an 'Erkundungstour' (exploration tour) is often slightly ironic or colloquial. You can recognize it when the context has nothing to do with wild animals, but rather with, for example, a company, a city, or a topic.

expedition
'die Expedition' and 'die Safari' can both be special trips into nature. 'Expedition' is used when a journey has a research or discovery purpose and often leads to an area that is hard to access. 'Safari' usually means a trip, often in Africa, where people observe or hunt wild animals. The words can be confused because both are connected with adventure, nature, and distant places. For animals in their natural environment, 'Safari' is more natural. For research and discovery, 'Expedition' is more precise.
