Reserves and national parks are the territories in which nature is preserved in its natural form, and on which the economic activity of a person is prohibited (although there are exceptions). The main goal of such establishments is to preserve rare species of living organisms and important natural objects. This is achieved by limiting the activities of people at the territory of such places.
Reserves are the areas protected with the most stringent regime. As a rule, they are closed from a free visit, although sometimes tourists are still allowed to visit reserves. But all they can do is to simply admire nature.
National parks are the areas protected with a more free regime. Here even economic activity of a person is permissible, however, in limited quantities. And, unlike nature reserves, everyone, who wants to, can visit national parks.
