Which term refers to a designated location where people gather for an activity?

The term that denotes a designated location where people gather for an activity is "Punto de encuentro." This phrase directly translates to "meeting point" in English and perfectly captures the essence of a specific spot chosen for people to come together for a shared purpose, such as an event, discussion, or social interaction.

In contrast, the other terms do not convey the same meaning. "Route" refers to a path or course taken to reach a destination and does not imply a gathering location. "Rest" typically refers to a state of relaxation or cessation of activity, rather than a physical place where people congregate. "Snack" denotes a small amount of food that is eaten between meals, which relates to food rather than a gathering point. Therefore, "Punto de encuentro" is the most suitable term in this context.
