The Trump administration has unveiled a new policy that will significantly increase costs for foreign tourists visiting some of the United States’ most iconic national parks. Effective from 2026, international visitors will be required to pay an additional $100 surcharge on top of the standard entry fees at 11 of the most popular parks, including the Grand Canyon and Yellowstone. Additionally, the annual pass for non-residents, granting access to all national parks, will more than triple in price, rising from $80 to $250.
