Ecotourism is a type of tourism that take place in natural areas and often involves trekking and staying in local villages, but tries to have only a little impact on the environment and culture. Many ecotourism projects are already being run now, especially in the north and south of the country, involving local people as guides or host. The government likes and support this kind of tourism for a number of reasons. It doesn't need lots of facilities to be built, it provides jobs in country areas, local people can interpret culture and traditions for the tourists, the local guides can help the tourists to act in an appropriate way with the local people, and the local people can also take responsibility for the safety of the tourists.
