Like many foreign words that end in '-ion', 'Expedition' (expedition) is feminine. This helps you remember the article 'die'. The ending often points to a process or event, which fits well with the meaning 'Reise' (journey).
Die Organisation einer Expedition erfordert viel Planung.
Organizing an expedition requires a lot of planning.
Whether the journey or the group of people is meant is often revealed by the verb. Verbs like 'planen' (to plan) or 'unternehmen' (to undertake) refer to the journey as a whole. Verbs like 'erreichen' (to reach) or 'entdecken' (to discover) refer to the group carrying out the action.
Wir müssen die Expedition zum Nordpol sorgfältig planen.
We have to carefully plan the expedition to the North Pole.
'Expedition' (expedition) is often combined with verbs like 'unternehmen' (to undertake), 'leiten' (to lead), or 'durchführen' (to carry out). You can also say 'auf Expedition gehen' (to go on an expedition).

journey / trip
'die Reise' and 'die Expedition' both have to do with traveling to another place. 'die Reise' is the normal, general word for vacation, work, or other trips over a longer distance. 'die Expedition' is much more specific: it usually has a research or discovery goal and often leads to a difficult or remote area. In addition, 'Expedition' can also mean the group taking part in it. The words can be confused because every expedition is a kind of trip. But not every trip is an expedition.
