"跟着向导游览的人" can be translated into English as "people following a tour guide for sightseeing" or, more concisely, "tour guide followers" (though the latter is a bit more informal and might not capture the full context of sightseeing as precisely as the first option).
The first translation, "people following a tour guide for sightseeing", is more descriptive and clearly conveys the meaning of individuals who are accompanying a tour guide on a sightseeing tour.
