Question

Group of people who travel together over a long distance.

Answer 1

A group of people who travel together over a long distance is often referred to as a "travel party," "travel group," or "tour group." In more specific contexts, they might also be called a "caravan," "expedition," or "troupe," depending on the nature of their journey and activities. If it's for a specific purpose, terms like "pilgrimage" (for religious journeys) or "safari" (for wildlife exploration) might apply as well.
