Instead of having big groups of travellers pouring down at the same attraction, travelling in small groups and individually helps divide the traffic flow, lessen the amount of people concentrating at one location, preventing overcrowding. Therefore, it will increase the chances for travellers to engage with local people and explore their culture.
Travel is not all about what a destination can do for you, but also what you can bring to the location. Each of us have to be mindful of the impact we might have while travelling.
