National parks are protected areas established to conserve natural beauty, wildlife, and cultural heritage. They provide a space for outdoor recreation, education, and scientific research. Visitors can enjoy activities like hiking, camping, and wildlife watching while experiencing diverse ecosystems. In many countries, national parks are managed by government agencies to ensure their preservation for future generations. Famous examples include Yellowstone National Park in the United States and Banff National Park in Canada. These parks play a crucial role in protecting biodiversity and promoting environmental awareness among the public.
