For example, concessions to private operators have been crucial for the tourism development of Foz do Iguagu National Park. It has allowed the building of tourism infrastructure such as parking places, a visitor centre, inner-park transport and provision of food and beverage service and leisure and adventure activities. Concessions of this kind have also been used in other major parks, such as Tijuca and Fernando de Noronha, and new concessions are planned in coming years (ICMBio, 2012b). All protected area categories but two are open to visitors, but many areas receive none or very few (some areas receive visitors but do not register or track visitation).
