National parks are areas designated by governments for conservation and recreation. The United States established the first national park, Yellowstone, in 1872. National parks protect natural landscapes and wildlife while providing educational and outdoor activities for visitors. Retezat National Park in Romania, established in 1935, contains over 60 mountain peaks and 100 glacial lakes within its 380 square kilometer area. It shelters old-growth forests and is designated as a UNESCO biosphere reserve. Fiordland National Park in New Zealand covers 12,500 square kilometers and protects glacially carved fiords, dolphins, seals, rare birds like the kakapo and kiwi, and is popular for climbing and hiking.
