Parque nacional
While access to national parks is free, there are strict rules governing the behaviour of visitors, in order to ensure adequate protection for these areas of outstanding natural beauty. The main national parks in Spain are the Coto de Doñana (Huelva), Ordesa (Huesca) and Delta del Ebro (Tarragona), while Latin America boasts los Glaciares (Argentina), Isla Cocos (Costa Rica), Darién (Panama) and Canaima (Venezuela).
