I think it's because nowadays, many people live in the city. They came to the city to find a job or to have the best opportunity in their lives. That leads to overpopulation in the city and leads to many problems: air pollution, lack of space... People in the city like to travel to the countryside where the air is clean. There are still not many people and many vehicles. They feel like it's peaceful. They don't have to rush into the busy life in the big cities. They can enjoy peaceful and simple moments. They can try local food and know the local people. Young people love to experiment with new things, and things in the city are just the same. Nowadays people also enjoy being in nature so the countryside is the best place to go.
